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. 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 Updated on 02-November-2015 1roc, 1wg3 – yASF – yeast 2idc – yASF/H3 1tey – hASF N terminal – human - NMR 2io5 – hASF + histone H3.1 + histone H4 2hue - yASF + histone H3 + histone H4 4eo5 - yASF + histone H3.2 (mutant) + histone H4 (mutant) 2z3f – yASF + SPCIA1 2i32 – hASF + HIRA 2z34 – hASF N terminal + HIR1 3aad – hASF + transcription initiation factor TFIID 2ygv – yASF + serine/threonine protein kinase RAD53
