OxTalks is Changing
OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
"Mechanistic and structural insights into protein complexes that regulate DNA repair and mRNA stability"
Almost every eukaryotic mRNA has a poly(A) tail which is added by a 1 MDa multi-protein complex called Cleavage and Polyadenylation Factor (CPF/CPSF). There are four different enzymes in CPF (nuclease, polymerase and two protein phosphatases) but it is not understood how these are co-ordinated to define mRNA 3′-ends and regulate transcription. In addition, it is not clear what makes the poly(A) RNA sequence unique. We use a combination of structural biology (cryo-EM, X-ray crystallography, NMR) and biochemical reconstitution to address these questions and to gain mechanistic insight.
