PIN1-SUMO2/3 motif suppresses excessive RNF168 chromatin accumulation and ubiquitin signaling to promote IR resistance - Nature Communications
The ubiquitin ligase, RNF168, promotes DNA break repair but must be regulated to prevent run-away ubiquitin signaling. Here, the authors identify a three-step post-translational cascade regulating RNF...

Fascinating work from @raychaudhurilab.bsky.social and @cejkalab.bsky.social! Challenges the idea that HR defects in BRCA2-deficient cells stem from poor RAD51 loading, shows instead that unchecked RAD51 removal by FIGNL1 drives the defect. Great read!
A tour de force by Raviprasad Kuthethur and amazing collaborations from @cejkalab.bsky.social ,Shyam Sharan and Krishna Mohan Poluri labs. Thanks a lot to Safa Nasrin, Satheesh Kumar Sengodan, Stefan Braunshier, Carmen Fonseca , Nupur Nagar, Ananya Acharya for putting it all together.

SUMO interactions: the 1st of two reviews which Aanchal (@origichals.bsky.social), El Hadji, and I have recently written on non-covalent interactions of SUMO is now out. The 1st covers interactions with E1, E2, and deSUMOylating enzymes; the 2nd - on interactions with SIMs etc. - will appear soon.

SUMOylation – a protein post-translational modification (PTM) related to ubiquitylation – involves the reversible covalent attachment of the small ubiquitin-like modifier (SUMO) to proteins. During th...

Excited to share our latest publication, out in @science.org! We define a key role for the CST complex in double-strand break repair pathway choice. This study was conducted in close collaboration with the Sung lab at UT Health San Antonio. Congrats to @michelleswift.bsky.social and all authors!
CTC1-STN1-TEN1 controls DNA break repair pathway choice via DNA end resection blockade
Antagonistic activities of the 53BP1 axis and the tumor suppressor BRCA1-BARD1 determine whether DNA double-strand breaks (DSBs) are repaired by end joining or homologous recombination. We show that t...
