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

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.

An eIF5/eIF2 complex antagonizes guanine nucleotide exchange by eIF2B during translation initiation.

Singh CR, Lee B, Udagawa T, Mohammad-Qureshi SS, Yamamoto Y, Pavitt GD, Asano K

In eukaryotic translation initiation, the eIF2.GTP/Met-tRNA(i)(Met) ternary complex (TC) binds the eIF3/eIF1/eIF5 complex to form the multifactor complex (MFC), whereas eIF2.GDP binds the pentameric factor eIF2B for guanine nucleotide exchange. eIF5 and the eIF2Bvarepsilon catalytic subunit possess a conserved eIF2-binding site. Nearly half of cellular eIF2 forms a complex with eIF5 lacking Met-tRNA(i)(Met), and here we investigate its physiological significance. ... [more]
