Function

ASF1_YEAST Histone chaperone that facilitates histone deposition and histone exchange and removal during nucleosome assembly and disassembly. Facilitates histone deposition through both replication-dependent and replication-independent chromatin assembly pathways. Cooperates with chromatin assembly factor 1 (CAF-1) to promote replication-dependent chromatin assembly and with the HIR complex to promote replication-independent chromatin assembly, which may occur during transcription and DNA repair. May be required for the maintenance of a subset of replication elongation factors, including DNA polymerase epsilon, the RFC complex and PCNA, at stalled replication forks. Also required for acetylation of histone H3 on 'Lys-9' and 'Lys-56'.^{[1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] [22] [23] [24] [25] [26] [27] [28] [29] [30] [31] [32] [33] [34] [35] [36] [37] [38] [39]}
