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

Synthetic Rescue
A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.
Publication
Genetic Analysis Implicates the Set3/Hos2 Histone Deacetylase in the Deposition and Remodeling of Nucleosomes Containing H2A.Z.
Histone variants and histone modification complexes act to regulate the functions of chromatin. In Saccharomyces cerevisiae the histone variant H2A.Z is encoded by HTZ1. Htz1 is dispensable for viability in budding yeast, but htz1Δ is synthetic sick or lethal with the null alleles of about 200 non-essential genes. One of the strongest of these interactions is with the deletion of ... [more]

Additional Notes
- High Throughput: A modified Synthetic Genetic Array (SGA) analysis involving triple mutants was carried out to assess the genome-wide suppression of htz1 negative genetic interactions. A double mutant query strain carrying a deletion of hda1 (suppressor) and an htz1 deletion was crossed against mini-arrays containing strains with known gene deletions that have negative genetic interactions with htz1 null mutants.
