ABC Science Updates: Could a blood donor be framed at a crime scene?

ABC Science Updates, 5 February 2009
Science Updates is a weekly email alert from the Australian Broadcasting Corporation (ABC)

== ASK AN EXPERT: COULD THE RECIPIENT OF DONATED BLOOD LEAVE THE DONOR'S DNA AT A CRIME SCENE? ==
As I am a regular blood donor is it possible for the recipient of my donated blood to leave my DNA at a crime scene if the recipient commits a crime and leaves blood at the scene?

== IN THE SKY THIS WEEK ==
The full Moon is Tuesday February 10. Late in the evening of Monday February 9, there is a shallow partial eclipse of the Moon. Observers will see a faint but noticeable darkening of the northern half of the Moon. The eclipse is at its maximum at 1:38am AEDST February 10 (11:38pm February 9 in WA). Venus is easily recognised as the brightest object in the Western evening sky, and is now a distinct crescent shape in small telescopes. Comet Lulin is now visible in binoculars, not far from Zubenelgenubi, the brightest star in Libra. In the coming week it may become just visible to the unaided eye under dark skies.

Saturn is now rising well before midnight and can be easily seen as the second brightest object above the north-eastern horizon, almost midway between the bright stars Regulus and Spica. In the late evening of February 8, Saturn's moon Titan makes a rare transit of the body of Saturn. For those of you with telescopes, or with friends with telescopes, this is an excellent event to watch. The transit starts shortly after midnight in the eastern states, and shortly after 10:00pm in WA. In the morning, Mercury can be seen clearly just below the 'teapot' of Sagittarius, Mars is more difficult to see below Mercury. By the end of the week Jupiter joins Mars in the twilight, and there will be a nice line-up of all three planets next week.

THE SCIENCE SHOW - Did young Charles tell fibs?
Saturday 7 February, 12.05pm & Monday 9 February, 7.05pm RN
There are two sides to evolution: deeply serious - and jolly good fun. The fun is provided by Dame Edna Everage who displays the immense variety of everything in the natural world. She also illustrates the way Darwinism hit the Music Hall stage in the 19th century giving rise to many kinds of outrageous acts, hoaxes and impersonations. Queensland-based writer Jane Goodall takes us on a tour of the razzmatazz - and along the way shows how Charles Darwin the boy was often given to deceptions and tease. And the serious part of this Science Show shows how the modern science of epigenetics and embryology maintain the wonder of Darwin's ideas.

THE PHILOSOPHER'S ZONE - Philosophy in the mountains
Saturday 7 February, 1.30pm & Monday 9 February, 1.35pm RN
Arne Næss, who died in January just a couple of weeks short of his ninety-seventh birthday, was a great mountaineer and part of the history of twentieth-century philosophy. He started out as a member of the great philosophical school the Vienna Circle but was better known as the founder of the movement known as deep ecology. This week, we pay tribute to the man and his work.

OCKHAM'S RAZOR - Economic fiction - how Homo sapiens could stop climate change
Sunday 8 February, 8.45am RN
Melbourne author Valerie Yule looks at the problem of waste which is anything that becomes useless rubbish before it needs to be. If we tackle the problem of excess in everyday life from food uneaten and thrown away to the use of disposables for convenience this is one way we could start cutting global carbon emissions very quickly.

BACKGROUND BRIEFING - Assisted death
Sunday 8 February, 9am & Tuesday10 February, 7pm RN
The law in Australia may not have caught up with modern medicine and doctors and the authorities are caught between a rock and a hard place. Dr Rodney Syme says the current situation of people who are terminally ill and in great pain is a scandal.
http://abcmail.net.au/t/386783/686964/911/0/

http://abcmail.net.au/t/386783/686964/3870/0/

FUTURE TENSE - IRENA enters the arena
Thursday 12 February, 8.30am & Friday 13 February, 12.30am RN
IRENA stands for the International Renewable Energy Agency. It's a new international body that's just been formed.

A high-mobility electron-transporting polymer for printed transistors
pp679-686
A range of plastic semiconductors have been developed that have the
combination of physical and chemical properties required to enable
printable electronic circuitry, but these are almost exclusively
'hole transporting' materials. If an electron-transporting equivalent
could be found, it could be combined with the existing classes of
materials to produce yet more powerful devices. This paper reports the
development of a such a material: the electron-transporting plastic
semiconductor exhibits unprecedented device performance, and is
compatible with a broad range of printing and processing technologies.

The unfolded protein response signals through high-order assembly of
Ire1 pp687-693
Accumulation of misfolded proteins results in the activation of the
unfolded protein response (UPR) in the endoplasmic reticulum. Ire1 is
important in this pathway and functions as a kinase and endoribonuclease.
This paper solves the crystal structure of Ire1 kinase and shows that it
undergoes spontaneous assembly into a rod-shaped oligomer. This
arrangement positions the kinase domains for trans-autophosphorylation,
orders the RNase domains and creates an interaction site for mRNA
substrate binding.

A kiloparsec-scale hyper-starburst in a quasar host less than 1 gigayear

The host galaxy of the quasar SDSS J114816.64+525150.3 has an infrared
luminosity of 2.2 1013 times that of the Sun. In the extremely luminous
'local' galaxy Arp 220, the burst of star formation is concentrated in
the relatively small central region of <100 pc radius. This study reports
that the star-forming gas of the host galaxy of J114816.64+525150.3 is
distributed over a radius of about 750 pc around the centre. The surface
density of the star formation rate averaged over this region is comparable
to the peak in Arp 220, although about two orders of magnitude larger in
area.

Holocene oscillations in temperature and salinity of the surface

This study investigates the temperature and salinity changes of

variations in temperature and salinity that correlate with previously
reported periods of rapid climate change. The inflow becomes more
saline during enhanced freshwater flux to the subpolar North Atlantic.
Model studies predict a weakening of Atlantic meridional overturning
circulation in response to enhanced Arctic freshwater fluxes, although
the inflow can compensate on decadal timescales by becoming more saline.

It is shown that after activation, Ire1 molecules cluster into discrete

HAC1 mRNA is recruited to these foci by means of a sequence in its 3'

or HAC1 mRNA recruitment impairs UPR signalling. Hence HAC1 mRNA is delivered
to a site where it is processed thus ensuring that it is only translated
when UPR is on.

Peptide neurotransmitters activate a cation channel complex of NALCN and
UNC-80 pp741-744
Substance P is a neuropeptide that evokes slow excitation after activation
of its cognate G-protein-coupled receptor. This study investigates the
downstream pathway and shows that it depends on Src family kinases, rather
than G-protein signalling.

Counting RAD51 proteins disassembling from nucleoprotein filaments
under tension pp745-748
DNA strand exchange results in a physical linkage between two homologous
DNAs. The RecA/RAD51 family of ATPases mediates strand exchange by forming
a long filament on the DNA. This paper uses a single-molecule approach to
elucidate how the filament is disassembled once the strands are exchanged,
and how this process relates to the energy released by nucleotide hydrolysis.

The year that was and the year ahead p99
Now that we are well into 2009, I can't help but think about the
year that has passed. Fear not, this will not be one of those
dreaded holiday letters where we list all the highs and lows of
the year. But as I look back, there are many things I hope that
I have permanently crossed off my 'To Do' list and others that I
am looking forward to doing.

Tip20p reaches out to Dsl1p to tether membranes pp100 - 102
Large, multisubunit complexes have been implicated in tethering
transport vesicles to organelle membranes before membrane fusion.
New structures add to the growing list of tethering complexes that
contain conserved helical bundle structures and provide a first
glimpse of how these complexes are assembled.

Wedging out DNA damage pp102 - 104
The DNA-repair machinery is faced with the significant challenge
of differentiating DNA lesions from unmodified DNA. Two recent
publications, one in this issue of Nature Structural & Molecular
Biology, uncover a new way of recognizing minimally distorting DNA
lesions: insertion of a 3- or 4-amino-acid wedge into DNA to extrude
the lesion into a shallow binding pocket that can accommodate
various damaged bases.

Towards the architecture of the chromosomal architects pp104 - 105
MukBEF, the bacterial prototype of eukaryotic condensins and
cohesins, has a key role in the global chromosomal organization of
Escherichia coli and its close relatives. The recent report of the
crystal structure of the MukB head domain in complex with its
accessory subunits MukEF clearly demonstrates that MukBEF functions
as a macromolecular assembly rather than a set of individual
molecules and offers clues on how ATP and MukEF regulate the
architecture of this complex.

Structural characterization of Tip20p and Dsl1p, subunits of the
Dsl1p vesicle tethering complex pp114 - 123
The Dsl1p tethering complex is crucial for Golgi-to-ER retrograde
trafficking of vesicles in yeast. The crystal structures of two out
of three Dsl1p complex components reveal similarity to exocyst and
COG complex components, which act in tethering vesicles to the
plasma membrane and Golgi, respectively, suggesting a conserved
tethering strategy at several eukaryotic membranes.

High-resolution dynamic mapping of histone-DNA interactions in a
nucleosome pp124 - 129
DNA packaging into nucleosomes presents a barrier to many motor
proteins, including the transcriptional machinery. By unzipping
DNA in single nucleosomes, a detailed map at near base pair
resolution of histone-DNA interactions is now provided, suggesting
that interaction with the two DNA strands is decoupled and that
unraveling past the dyad axis of the nucleosome, as might occur
when a motor protein passes through, is sufficient to displace
histones.

Using CLIP-seq technology, the genome-wide binding sites of the FOX2

identified. Further work based on FOX2 depletion uncovers the
underlying logic of FOX2-mediated regulation of alternative splicing
and finds that such compromised hESCs undergo rapid cell death.

Structures of endonuclease V with DNA reveal initiation of deaminated
adenine repair pp138 - 143
Endonuclease V can initiate the repair of deaminated purine bases by
recognizing them and hydrolyzing the second phosphodiester bond on
their 3' side. Now the crystal structures of endonuclease V in complex
with its substrate and its product reveal a wedge motif acting as a
minor groove-damage sensor and a pocket to recognize the lesion; the
enzyme remains tightly bound to the 5' phosphate product, perhaps to
hand it over to downstream repair factors.

Biological basis for restriction of microRNA targets to the 3'
untranslated region in mammalian mRNAs pp144 - 150
MicroRNA target sites tend to reside in the 3' untranslated regions
of transcripts in animals. By altering the stop codon position in a
model target and thus placing miRNA target sites within open reading
frames, it is now found that translation through a miRNA target
region is refractory to miRNA-mediated repression.

Nucleosomes can invade DNA territories occupied by their neighbors
pp151 - 158
Nucleosomes can be closely spaced in vivo, suggesting that they may
on occasion approach one another or even meet. Using in vitro
dinucleosomal model systems, positioned nucleosomes, as well as
nucleosomes in the process of being repositioned, are now shown to
overlap, forming single, compact particles, with one histone dimer
ejected in the process. The potential relevance to remodeling
processes is discussed.

SRS2 and SGS1 prevent chromosomal breaks and stabilize triplet
repeats by restraining recombination pp159 - 167
Triple expansions underlie a number of human disorders. Triplet
repeat instability in yeast mutants for the Srs2 and Sgs1 helicases
indicate that recombination underlies instability in such a genetic
background. Further analysis of replication intermediates indicates
that Srs2 is likely to be involved in replication fork reversal
within repetitive sequences, a process involved in preventing repeat
instability and fragility.

Helix movement is coupled to displacement of the second extracellular

Crystal structures of the visual pigment rhodopsin have revealed

second extracellular loop (EL2) is important in maintaining inactive
receptor conformations and for propagating conformational changes
associated with photoactivation to the rest of the protein.

Recognition of atypical 5' splice sites by shifted base-pairing to
U1 snRNA pp176 - 182
One of the key early steps in splicing is recognition of the 5'
splice site by base-pairing to the U1 small nuclear RNA. Data now
indicate that U1 can shift to recognize what had been designated as
atypical 5' splice sites, broadening the scope of what can be
recognized as a functional splice site by the canonical machinery
and thus impacting both splicing predictions and mechanism, as well
as providing a potential mechanism underlying a puzzling mutation
associated with pontocerebellar hypoplasia.

A distinct class of small RNAs arises from pre-miRNA-proximal
regions in a simple chordate pp183 - 189
Small RNAs are involved in the regulation of gene expression. During
a hunt for microRNAs in the simple chordate Ciona intestinalis, a
distinct class of small RNAs, offset from the microRNA expressed
from a given hairpin, have been defined. These offset small RNAs
are expressed in relative abundance in C. intestinalis and are also
detected at specific developmental stages. Although their function i
s unclear, these results suggest that microRNA processing has
distinct properties in this simple organism.

Conformational flexibility of metazoan fatty acid synthase enables
catalysis pp190 - 197
Fatty acid synthase is composed by several catalytic domains that
work in sequence, with reaction intermediates being transferred
between them. Single-particle EM analysis of different catalytic
mutants of rat FAS imaged in the presence of substrates reveals
the domains' movements during the reaction cycle.

MIA40 is an oxidoreductase that catalyzes oxidative protein folding
in mitochondria pp198 - 206
MIA40, found in the mitochondrial intermembrane space, is a central
component in the import system that transports certain cysteine
motif-containing proteins into the mitochondria. New analyses
reveal that MIA40 forms a novel thioredoxin fold. Its redox center
catalyzes the formation of the first disulfide bond of a substrate,
causing the susbtrate's second disulfide to require only oxygen for
its formation.

RDE-1 slicer activity is required only for passenger-strand cleavage
during RNAi in Caenorhabditis elegans pp207 - 211
RDE-1 is a Caenorhabditis elegans Argonaute homolog involved in
mediating the primary response to small RNA interference. Analyses
now indicate that the RNase H-homologous region of RDE-1 is not
needed for target cleavage, but is specifically required for
removing the passenger strand of fully complementary siRNA duplexes.

Nucleic acid polymerases use a general acid for nucleotidyl transfer
pp212 - 218
Nucleic acid polymerases catalyze nucleotidyl transfer reactions with
two proton-transfer events, deprotonation of the 3'-hydroxyl
nucleophile and protonation of the pyrophosphate leaving group.
Functional analyses now show that the proton donor for the latter
transfer is an active-site residue.

Polyubiquitin substrates allosterically activate their own
degradation by the 26S proteasome pp219 - 225
Activation of the 20S proteasome requires the binding of regulatory
proteins such as the 19S regulatory particle, which opens the 20S
gates allowing substrate access to the active sites. New data now
indicate that binding of a polyubiquitylated substrate to the 19S
particle allows further opening of the 20S gates, suggesting a
feedforward mechanism for 20S activation.

BRIEF COMMUNICATION

Replisome stalling and stabilization at CGG repeats, which are
responsible for chromosomal fragility pp226 - 228
Expanded CGG repeats cause chromosomal fragility and hereditary
neurological disorders in humans. These repeats adopt unusual
structures that block DNA replication in vitro and in unicellular
organisms. Mirkin and co-workers asked whether the same holds true
in mammalian cells. They find that CGG repeats stall replication
forks in a length-dependent, but orientation-independent, manner
and do not seem to trigger an intra-S phase checkpoint response.
They suggest that fragile sites arise because the cell cycle
continues before replication is complete and the under-replicated
areas would convert into constrictions and/or double-stranded breaks.
