Chromatin assembly factor 1 subunit A (CHAF1A)

Core part of the CAF-1 complex, a complex thought to mediate chromatin assembly in DNA replication and DNA repair. Assembles histone octamers onto replicating DNA in vitro.

CAF-1 performs the initial step of the nucleosome assembly process, bringing newly synthesized histones H3 and H4 to replicating DNA; histones H2A/H2B can bind to this chromatin precursor following DNA replication to finish the histone octamer. CHAF1A binds to histones H3 and H4.
