ZHP-2/HEI10 generates CO precursors and triggers procrossover factor coarsening and CO formation through Polo kinase recruitment

Alyssa Centonza-Brenie, Ryan Dawson, Sowmya Geetha, Aya Sato-Carlton, Peter Mark Carlton, Verena Jantsch, Monique Zetka

This study shows ZHP-2/HEI10 regulates CO formation in C. elegans by disassembling proCO factors and recruiting Polo kinase to trigger coarsening and crossover execution.
