DESCRIPTION

Also known as FANCM_HUMAN, FANCM, KIAA1596. DNA-dependent ATPase component of the Fanconi anemia (FA) core complex (PubMed:16116422). Required for the normal activation of the FA pathway, leading to monoubiquitination of the FANCI-FANCD2 complex in response to DNA damage, cellular resistance to DNA cross-linking drugs, and prevention of chromosomal breakage (PubMed:16116422, PubMed:19423727, PubMed:20347428, PubMed:20347429, PubMed:29231814). In complex with CENPS and CENPX, binds double-stranded DNA (dsDNA), fork-structured DNA (fsDNA) and Holliday junction substrates (PubMed:20347428, PubMed:20347429). Its ATP-dependent DNA branch migration activity can process branched DNA structures such as a movable replication fork. This activity is strongly stimulated in the presence of CENPS and CENPX (PubMed:20347429). In complex with FAAP24, efficiently binds to single-strand DNA (ssDNA), splayed-arm DNA, and 3'-flap substrates (PubMed:17289582). In vitro, on its own, strongly binds ssDNA oligomers and weakly fsDNA, but does not bind to dsDNA (PubMed:16116434). Component of the Fanconi anemia (FA) core complex, which consists of CENPS, CENPX, FANCA, FANCB, FANCC, FANCE, FANCF, FANCG, FANCL, FANCM, FAAP24 and FAAP100 (PubMed:16116422, PubMed:16116434, PubMed:17289582). The FA core complex associates with Bloom syndrome (BLM) complex, which consists of at least BLM, DNA topoisomerase 3-alpha/TOP3A, RMI1/BLAP75, RPA1/RPA70 and RPA2/RPA32. This supercomplex between FA and BLM complexes has been called BRAFT (PubMed:20347428). Forms a discrete complex with CENPS and CENPX, called FANCM-MHF; this interaction stimulates DNA binding and replication fork remodeling by FANCM and stabilizes the binding partners (PubMed:20347428, PubMed:20347429). Forms a heterodimer with FAAP24; this interaction increases FANCM single-stranded DNA-binding activity (PubMed:17289582, PubMed:20347428).
