| - | [[ | + | [[https://www.uniprot.org/uniprot/ASF1_YEAST 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'.<ref>PMID:9290207</ref> <ref>PMID:10591219</ref> <ref>PMID:11412995</ref> <ref>PMID:11331602</ref> <ref>PMID:11731479</ref> <ref>PMID:11731480</ref> <ref>PMID:11404324</ref> <ref>PMID:11172707</ref> <ref>PMID:11856374</ref> <ref>PMID:11756556</ref> <ref>PMID:12093919</ref> <ref>PMID:14585955</ref> <ref>PMID:15071494</ref> <ref>PMID:15452122</ref> <ref>PMID:15175160</ref> <ref>PMID:15542829</ref> <ref>PMID:15542840</ref> <ref>PMID:15766286</ref> <ref>PMID:16303565</ref> <ref>PMID:15821127</ref> <ref>PMID:15901673</ref> <ref>PMID:16020781</ref> <ref>PMID:16143623</ref> <ref>PMID:16039596</ref> <ref>PMID:15632066</ref> <ref>PMID:15891116</ref> <ref>PMID:16141196</ref> <ref>PMID:15840725</ref> <ref>PMID:16815704</ref> <ref>PMID:16936140</ref> <ref>PMID:16582440</ref> <ref>PMID:16407267</ref> <ref>PMID:17046836</ref> <ref>PMID:16678113</ref> <ref>PMID:16501045</ref> <ref>PMID:16627621</ref> <ref>PMID:17107956</ref> <ref>PMID:17320445</ref> <ref>PMID:14680630</ref> [[https://www.uniprot.org/uniprot/H4_XENLA H4_XENLA]] Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. |
