PRE9

proteasome core particle subunit alpha 3, L000002701, YGR135W
Alpha 3 subunit of the 20S proteasome; the only nonessential 20S subunit; may be replaced by the alpha 4 subunit (Pre6p) under stress conditions to create a more active proteasomal isoform

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.

Genetic Analysis Implicates the Set3/Hos2 Histone Deacetylase in the Deposition and Remodeling of Nucleosomes Containing H2A.Z.

Hang M, Smith MM

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]

Ontology Terms

  • phenotype: colony size (APO:0000063)

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 pre9 (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.
