TPK1

PKA1, SRA3, cAMP-dependent protein kinase catalytic subunit TPK1, L000002045, YJL164C
cAMP-dependent protein kinase catalytic subunit; promotes vegetative growth in response to nutrients via the Ras-cAMP signaling pathway; inhibited by regulatory subunit Bcy1p in the absence of cAMP; phosphorylates and inhibits Whi3p to promote G1/S phase passage; partially redundant with Tpk2p and Tpk3p; phosphorylates pre-Tom40p, which impairs its import into mitochondria under non-respiratory conditions; TPK1 has a paralog, TPK3, that arose from the whole genome duplication

DOA1

UFD3, ZZZ4, L000002961, YKL213C
WD repeat protein required for ubiquitin-mediated protein degradation; forms a complex with Cdc48p; plays a role in controlling cellular ubiquitin concentration; also promotes efficient NHEJ in postdiauxic/stationary phase; facilitates N-terminus-dependent proteolysis of centromeric histone H3 (Cse4p) for faithful chromosome segregation; protein increases in abundance and relocalizes from nucleus to nuclear periphery upon DNA replication stress

Synthetic Growth Defect

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

Deletion of yeast TPK1 reduces the efficiency of non-homologous end joining DNA repair.

Hooshyar M, Jessulat M, Burnside D, Kluew A, Babu M, Golshani A

Non-homologous end joining (NHEJ) is a highly conserved mechanism of DNA double-stranded break (DSB) repair. Here we utilize a computational protein-protein interaction method to identify human PRKACB as a potential candidate interacting with NHEJ proteins. We show that the deletion of its yeast homolog, TPK1 that codes for the protein kinase A catalytic subunit reduces the efficiency of NHEJ repair ... [more]
