HDA1

histone deacetylase HDA1, L000004088, YNL021W
Putative catalytic subunit of a class II histone deacetylase complex; role in azole resistance via Hsp90p, and in the heat shock response; Hda1p interacts with the Hda2p-Hda3p subcomplex to form an active tetramer; deletion increases histone H2B, H3 and H4 acetylation; other members of the HDA1 histone deacetylase complex are Hda2p and Hda3p
Saccharomyces cerevisiae (S288c)

Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

An Uncharacterized Domain Within the N-Terminal Tail of Histone H3 Regulates the Transcription of FLO1 via Cyc8.

Singh R, Tomar RS

Yeast flocculation relies on cell surface flocculin proteins encoded by the sub-telomeric gene, FLO1. The expression of FLO1 is antagonistically regulated by the Tup1-Cyc8 repressor complex and the Swi-Snf co-activator complexes. The role of hyperacetylated N-terminal amino acid residues of histone H3 and H4 is well established in the transcription of FLO1 and other Tup1-Cyc8 regulated genes. However, sub-domains within ...

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
