ASF cooperates with chromatin assembly factor 1 (CAF-1) to promote replication-dependent chromatin assembly and with histone regulatory homolog A (HIRA) to promote replication-independent assembly.[1] Structural highlights ASF has an 80 residue segment which binds RNA at the N-terminal and a C-terminal which is composed of 80% Ser and Arg. 3D structures of anti-silencing factor Anti-silencing factor 3D structures
