HHT2

histone H3, L000000773, YNL031C
Histone H3; core histone protein required for chromatin assembly, part of heterochromatin-mediated telomeric and HM silencing; one of two identical histone H3 proteins (see HHT1); regulated by acetylation, methylation, and phosphorylation; H3K14 acetylation plays an important role in the unfolding of strongly positioned nucleosomes during repair of UV damage

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Dynamic histone acetylation is critical for cotranscriptional spliceosome assembly and spliceosomal rearrangements.

Gunderson FQ, Merkhofer EC, Johnson TL

Assembly of the spliceosome onto pre-mRNA is a dynamic process involving the ordered exchange of snRNPs to form the catalytically active spliceosome. These ordered rearrangements have recently been shown to occur cotranscriptionally, while the RNA polymerase is still actively engaged with the chromatin template. We previously demonstrated that the histone acetyltransferase Gcn5 is required for U2 snRNP association with the ... [more]

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.
