Fanconi anemia group D2 protein homolog

UniProtKB accession:  Q80V62

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Required for maintenance of chromosomal stability (PubMed:12893777). Promotes accurate and efficient pairing of homologs during meiosis (By similarity). Involved in the repair of DNA double-strand breaks, both by homologous recombination and single-strand annealing (By similarity). The FANCI-FANCD2 complex binds and scans double-stranded DNA (dsDNA) for DNA damage; this complex stalls at DNA junctions between double-stranded DNA and single-stranded DNA (By similarity). May participate in S phase and G2 phase checkpoint activation upon DNA damage (By similarity). Plays a role in preventing breakage and loss of missegregating chromatin at the end of cell division, particularly after replication stress (By similarity). Promotes BRCA2/FANCD1 loading onto damaged chromatin (By similarity). May also be involved in B-cell immunoglobulin isotype switching (By similarity).
