New work from the lab! We report that DDIAS is a downstream effector of CIP2A-TOPBP1 in mitosis that suppresses ssDNA to preserve genome integrity. From the great @yiboxue.bsky.social and many collaborators! Free link: authors.elsevier.com/a/1nfiF3vVUP... Pay link: www.cell.com/molecular-ce...

Happy to share that I will be joining the Biology Department and Holden Comprehensive Cancer Center at University of Iowa as an assistant professor in summer 2027! My lab will study how recombination is regulated to prevent non-allelic repair and genome rearrangements, and their relation to cancer.

Carolyn started this as a whole-genome revisit of the classic 1996 papers on spontaneous nondisjunction from Hawley (Dros X) and Sherman (human 21) labs. She looked at a metacentric (Dros 2) and found that the rules are different - no obvious relationship between ndj and crossovers. Shape matters!

Happy to share our collaborative project with Stephane Marcand, on the protective role of Rap1 at telomeres. It turned out that our favorite protein, MRX, has the ability to measure telomere length, and activate response pathways when telomeres become too short. www.nature.com/articles/s41...

See our paper “Mechanism of trinucleotide repeat expansion by MutSβ-MutLγ and contraction by FAN1”. Using biochemistry, we show how DNA incisions by the MutLγ nuclease can lead to expansions, and how expansion is prevented by FAN1. Well done Issam and Valentina! www.nature.com/articles/s41...
