[https://www.uniprot.org/uniprot/ASF1A_HUMAN ASF1A_HUMAN] Histone chaperone that facilitates histone deposition and histone exchange and removal during nucleosome assembly and disassembly. Cooperates with chromatin assembly factor 1 (CAF-1) to promote replication-dependent chromatin assembly and with HIRA to promote replication-independent chromatin assembly. Required for the formation of senescence-associated heterochromatin foci (SAHF) and efficient senescence-associated cell cycle exit.<ref>PMID:10759893</ref> <ref>PMID:11897662</ref> <ref>PMID:12842904</ref> <ref>PMID:14718166</ref> <ref>PMID:15621527</ref> <ref>PMID:16151251</ref> <ref>PMID:15664198</ref>

== Publication Abstract from PubMed ==
 +
In the search for foldamer inhibitors of the histone chaperone ASF1, we explored the possibility of substituting four alpha-residues ( approximately one helix turn) by 3-urea segments and scanned the sequence of a short alpha-helical peptide known to bind ASF1. By analysing the impact of the different foldamer replacements within the peptide chain, we uncovered new binding modes of the peptide-urea chimeras to ASF1.
