Summary: Enables DNA binding activity. Involved in chromosome condensation; regulation of nucleobase-containing compound metabolic process; and sporulation. Acts upstream of or within regulation of double-strand break repair. Located in chromatin and nucleus. Human ortholog(s) of this gene implicated in acute lymphoblastic leukemia. Orthologous to several human genes including H1-0 (H1.0 linker histone). [provided by Alliance of Genome Resources, Dec 2024]

Title: Hho1p, the linker histone of Saccharomyces cerevisiae, is important for the proper chromatin organization in vivo.
Hho1 may play a dual role during sporulation: Hho1 and Ume6 depletion facilitates the onset of meiosis via activation of Ume6-repressed early meiotic genes, whereas Hho1 enrichment in mature spores contributes to spore genome compaction.

mode of Hho1p action is similar to that of canonical linker histones
Title: Saccharomyces cerevisiae linker histone Hho1p functionally interacts with core histone H4 and negatively regulates the establishment of transcriptionally silent chromatin.
Hho1p has a limited role in transcriptional regulation; this dynamically exchanging linker histone may be evicted from chromatin by transcriptional activity.
Title: The Saccharomyces cerevisiae linker histone Hho1p is essential for chromatin compaction in stationary phase and is displaced by transcription.

Preferred Names: histone H1

NP_015198.1

Histone H1, linker histone with roles in meiosis and sporulation; decreasing levels early in sporulation may promote meiosis, and increasing levels during sporulation facilitate compaction of spore chromatin; binds to promoters and within genes in mature spores; may be recruited by Ume6p to promoter regions, contributing to transcriptional repression outside of meiosis; suppresses DNA repair involving homologous recombination
