ASF1 (P32447) - Overview - Molecular Target Synopsis


ASF1, Histone chaperone ASF1
UniProt P32447

Also Known as ASF1_YEAST, ASF1, CIA1

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'. Interacts with histone H3/H4 heterodimers via both histone H3 and histone H4. Interacts with RAD53 and this may impair interaction with histones and chromatin assembly. Interaction with RAD53 is reduced upon activation of DNA damage or replication checkpoints and loss of RAD53 may in turn facilitate interaction with histones and chromatin assembly. Interacts with the CAC2 subunit of chromatin assembly factor 1 (CAF-1). Interacts with the HIR1, HIR2, HIR3 and HPC2 subunits of the HIR complex. Interacts with the RFC1, RFC2, RFC3, RFC4 and RFC5 subunits of the replication factor C (RF-C/RFC) complex. The RF-C complex may recruit this protein to DNA. Interacts with the SAS2, SAS4 and SAS5 subunits of the SAS/SAS-I complex. Interacts with the BDF1, BDF2, SPT15, TAF1 and TAF7 subunits of the TFIID complex. Interacts with RTT109.
