CSM2/YIL132C Summary Help

Standard Name CSM2 1
Systematic Name YIL132C
Feature Type ORF, Verified
Description Component of Shu complex (aka PCSS complex); Shu complex also includes Psy3, Shu1, Shu2, and promotes error-free DNA repair,; Shu complex mediates inhibition of Srs2p function; promotes formation of Rad51p filaments; Psy3p and Csm2p contain similar DNA-binding regions which work together to form a single DNA binding site; required for accurate chromosome segregation during meiosis (1, 2, 3, 4, 5, 6)
Name Description Chromosome Segregation in Meiosis 1
