Function

DNA-binding component of the FA core complex involved in DNA damage repair and genome maintenance. Required for optimal chromatin association of the FA core complex. Required for efficient damage-induced monoubiquitination and focus formation of FANCD2. Stabilizes FAAD24, FANCM and APITD1/CENPS in the FA core complex. Plays a role in DNA interstrand cross-linking (ICL) repair and in recovery of replication forks stalled by topoisomerase I-DNA cleavage intermediates induced by camptothecin. Component of the heterotetrameric CENP-T-W-S-X complex that binds and supercoils DNA, and plays an important role in kinetochore assembly. Component of the APITD1/CENPS complex that is essential for the stable assembly of the outer kinetochore. Plays an important role in mitotic progression and chromosome segregation. Component of the CENPA-CAD (nucleosome distal) complex, a complex recruited to centromeres which is involved in assembly of kinetochore proteins, mitotic progression and chromosome segregation (By similarity). {ECO:0000250}.

Subcellular Localization

Nucleus {ECO:0000250}. Chromosome, centromere {ECO:0000250}. Chromosome, centromere, kinetochore {ECO:0000250}. Note=Constitutively localizes to centromeres throughout the cell cycle, and to kinetochores during mitosis. The CENPA-CAD complex is probably recruited on centromeres by the CENPA-NAC complex (By similarity). {ECO:0000250}.
