Is predicted to encode a protein with the following domains: twin BRCT domain; BRCT domain; BRCA1 C Terminus (BRCT) domain; BRCT domain superfamily; and BRCT domain, a BRCA1 C-terminus domain. Is an ortholog of C. elegans mus-101. In C. elegans, mus-101 is involved in several processes, including DNA damage response; DNA-templated DNA replication; and germ cell proliferation.
