[[http://www.uniprot.org/uniprot/HIRA_HUMAN HIRA_HUMAN]] Cooperates with ASF1A to promote replication-independent chromatin assembly. Required for the periodic repression of histone gene transcription during the cell cycle.

[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>
