FEATURES

DESCRIPTION

Also known as FACD2_HUMAN, FANCD2, FACD. Required for maintenance of chromosomal stability. Promotes accurate and efficient pairing of homologs during meiosis. Involved in the repair of DNA double-strand breaks, both by homologous recombination and single-strand annealing. May participate in S phase and G2 phase checkpoint activation upon DNA damage. Plays a role in preventing breakage and loss of missegregating chromatin at the end of cell division, particularly after replication stress. Required for the targeting, or stabilization, of BLM to non-centromeric abnormal structures induced by replicative stress. Promotes BRCA2/FANCD1 loading onto damaged chromatin. May also be involved in B-cell immunoglobulin isotype switching. Interacts directly with FANCE and FANCI. Interacts with USP1 and MEN1. The ubiquitinated form specifically interacts with BRCA1 and BLM. Both the nonubiquitinated and the monoubiquitinated forms interact with BRCA2; this interaction is mediated by phosphorylated FANCG and the complex also includes XCCR3. The ubiquitinated form specifically interacts with MTMR15/FAN1 (via UBZ-type zinc finger), leading to recruit MTMR15/FAN1 to sites of DNA damage. Interacts with DCLRE1B/Apollo (PubMed:11239454, PubMed:12093742, PubMed:12649160, PubMed:12874027, PubMed:15115758, PubMed:15199141, PubMed:15257300, PubMed:15694335, PubMed:17412408, PubMed:17460694, PubMed:18212739, PubMed:18469862, PubMed:20603015, PubMed:20603016, PubMed:20603073). Interacts with POLN (PubMed:19995904). Interacts with UHRF1 and UHRF2; these interactions promote FANCD2 activation (PubMed:30335751).
