HOS2

RTL1, histone deacetylase HOS2, L000004092, L000003448, YGL194C
Histone deacetylase and subunit of Set3 and Rpd3L complexes; required for gene activation via specific deacetylation of lysines in H3 and H4 histone tails; subunit of the Set3 complex, a meiotic-specific repressor of sporulation specific genes that contains deacetylase activity; co-localizes with Cmr1p in nuclear foci in response to DNA damage by MMS
Saccharomyces cerevisiae (S288c)
PREY

HAC1

ERN4, IRE15, transcription factor HAC1, L000002611, YFL031W
Basic leucine zipper (bZIP) transcription factor (ATF/CREB1 homolog); regulates the unfolded protein response, via UPRE binding, and membrane biogenesis; ER stress-induced splicing pathway facilitates efficient Hac1p synthesis; protein abundance increases in response to DNA replication stress
Saccharomyces cerevisiae (S288c)

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.

Hos2p/Set3p deacetylase complex signals secretory stress through the Mpk1p cell integrity pathway.

Cohen TJ, Mallory MJ, Strich R, Yao TP

Perturbations in secretory function activate stress response pathways critical for yeast survival. Here we report the identification of the Hos2p/Set3p deacetylase complex (SET3C) as an essential component of the secretory stress response. Strains lacking core components of the Hos2p/Set3p complex exhibit hypersensitivity to secretory stress. Although not required for the unfolded protein response (UPR) and ribosomal gene repression, the Hos2p ... [more]
