PSY3 is one of the components of the yeast Shu complex that maintains genomic stability during replication. Psy3 complexes first with Cms2, and their L2 loops confer the DNA-binding activity to the Shu complex [1,2]. The Shu complex binds to recombination sites and is required for Rad51 assembly and function during meiosis. The heterodimer of Psy3-Csm2 stabilises the Rad51-single-stranded DNA complex independently of nucleotide cofactor because Psy3-Csm2 is a structural mimic of the Rad51-dimer [3].	Domain

More than one copy is sometimes found in each protein. This family includes KaiC, which is one of the Kai proteins among which direct protein-protein association may be a critical process in the generation of circadian rhythms in cyanobacteria [1].
