DNA-binding component of the Fanconi anemia (FA) core complex. 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. In complex with CENPS (MHF heterodimer), crucial cofactor for FANCM in both binding and ATP-dependent remodeling of DNA. Stabilizes FANCM. In complex with CENPS and FANCM (but not other FANC proteins), rapidly recruited to blocked forks and promotes gene conversion at blocked replication forks. In complex with CENPS, CENPT and CENPW (CENP-T-W-S-X heterotetramer), involved in the formation of a functional kinetochore outer plate, which is essential for kinetochore-microtubule attachment and faithful mitotic progression. As a component of MHF and CENP-T-W-S-X complexes, binds DNA and bends it to form a nucleosome-like structure. DNA-binding function is fulfilled in the presence of CENPS, with the following preference for DNA substates: Holliday junction > double-stranded > splay arm > single-stranded. Does not bind DNA on its own.By similarity

Heterodimer with CENPX, sometimes called MHF; this interaction stabilizes both partners. MHF heterodimers can assemble to form tetrameric structures. MHF also coassemble with CENPT-CENPW heterodimers at centromeres to form the tetrameric CENP-T-W-S-X complex. Forms a discrete complex with FANCM and CENPX, called FANCM-MHF; this interaction, probably mediated by direct binding between CENPS and FANCM, leads to synergistic activation of double-stranded DNA binding and strongly stimulates FANCM-mediated DNA remodeling. Recruited by FANCM to the Fanconi anemia (FA) core complex, which consists of CENPS, CENPX, FANCA, FANCB, FANCC, FANCE, FANCF, FANCG, FANCL, FANCM, FAAP24 and FAAP100. 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. The super complex between FA and BLM is called BRAFT.By similarity
