GCN2

AAS1, AAS102, NDR2, serine/threonine-protein kinase GCN2, L000000681, YDR283C
Protein kinase; phosphorylates the alpha-subunit of translation initiation factor eIF2 (Sui2p) in response to starvation; activated by uncharged tRNAs and the Gcn1p-Gcn20p complex; contributes to DNA damage checkpoint control

GCD6

L000000674, YDR211W
Catalytic epsilon subunit of the translation initiation factor eIF2B; eIF2B is the guanine-nucleotide exchange factor for eIF2; activity subsequently regulated by phosphorylated eIF2; first identified as a negative regulator of GCN4 expression; forms cytoplasmic foci upon DNA replication stress

Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

Publication

The beta/Gcd7 subunit of eukaryotic translation initiation factor 2B (eIF2B), a guanine nucleotide exchange factor, is crucial for binding eIF2 in vivo.

Dev K, Qiu H, Dong J, Zhang F, Barthlme D, Hinnebusch AG

Eukaryotic translation initiation factor 2B (eIF2B) is the guanine nucleotide exchange factor (GEF) for eukaryotic translation initiation factor 2, which stimulates formation of the eIF2-GTP-Met-tRNA(i)(Met) ternary complex (TC) in a manner inhibited by phosphorylated eIF2 [eIF2(αP)]. While eIF2B contains five subunits, the ε/Gcd6 subunit is sufficient for GEF activity in vitro. The δ/Gcd2 and β/Gcd7 subunits function with α/Gcn3 in ... [more]
