Component of the HIR complex; which cooperates with ASF1 to promote replication-independent chromatin assembly. The HIR complex is also required for the periodic repression of three of the four histone gene loci during cell cycle as well as for autogenous regulation of the HTA1-HTB1 locus by H2A and H2B. DNA- binding by the HIR complex may repress transcription by inhibiting nucleosome remodeling by the SWI/SNF complex. The HIR complex may also be required for transcriptional silencing of centromeric; telomeric and mating-type loci in the absence of CAF-1. {ECO:0000269|PubMed:10445029; ECO:0000269|PubMed:11404324; ECO:0000269|PubMed:11412995; ECO:0000269|PubMed:11756556; ECO:0000269|PubMed:11782447; ECO:0000269|PubMed:11937489; ECO:0000269|PubMed:12524332; ECO:0000269|PubMed:12975325; ECO:0000269|PubMed:15057281; ECO:0000269|PubMed:16020781; ECO:0000269|PubMed:16039596; ECO:0000269|PubMed:16264190; ECO:0000269|PubMed:16303565; ECO:0000269|PubMed:16449659; ECO:0000269|PubMed:8417331; ECO:0000269|PubMed:9001207; ECO:0000269|PubMed:9504914; ECO:0000269|PubMed:9671488; ECO:0000269|PubMed:9671489}.
