inactivation of the negative regulatory system by deletion of the HIR1 gene relieved the dependence of HTA1-HTB1 transcription on the mitotic Clb1/Cb2 cyclins
Title: The mitotic Clb cyclins are required to alleviate HIR-mediated repression of the yeast histone genes at the G1/S transition.

nucleosome shielding is the primary means to maintain promoter fidelity, and histone replacement is most efficiently mediated in yeast cells by a HIR/Asf1/H3-H4/Rtt106 pathway.
Title: The replication-independent histone H3-H4 chaperones HIR, ASF1, and RTT106 co-operate to maintain promoter fidelity.

Asf1 and HIR are important for histone deposition but each has a different effect on histone exchange
Title: Histone chaperones regulate histone exchange during transcription.

overexpression of HIR1 in the Kllsm4Delta1 mutant prevented rapid cell death during aging, reduced nuclei fragmentation & increased resistance to H2O2; expression of histone genes is lowered in the mutant indicating a relationship between HIR1 & apoptosis
Title: HIR1, the co-repressor of histone gene transcription of Saccharomyces cerevisiae, acts as a multicopy suppressor of the apoptotic phenotypes of the LSM4 mRNA degradation mutant.

Restoration of silencing to CAF-1 subunit cac1 Delta cells requires both Hir1 and Asf1
Title: Regulation of histone deposition proteins Asf1/Hir1 by multiple DNA damage checkpoint kinases in Saccharomyces cerevisiae.
