SUI2

translation initiation factor eIF2 subunit alpha, L000002178, YJR007W
Alpha subunit of the translation initiation factor eIF2; eIF2 is involved in identification of the start codon; phosphorylation of Ser51 is required for regulation of translation by inhibiting the exchange of GDP for GTP; protein abundance increases in response to DNA replication stress
Saccharomyces cerevisiae (S288c)

GCN3

AAS2, translation initiation factor eIF2B subunit alpha, L000000682, YKR026C
Alpha subunit of translation initiation factor eIF2B; guanine-nucleotide exchange factor for eIF2; activity subsequently regulated by phosphorylated eIF2; positive regulator of GCN4 expression; assembles into filaments with Gcd2p, Gcd6p, Gcd7p, and Sui2p as cells approach stationary phase and under cytosolic acidification and starvation conditions
Saccharomyces cerevisiae (S288c)

Co-fractionation

Interaction inferred from the presence of two or more protein subunits in a partially purified protein preparation. If co-fractionation is demonstrated between 3 or more proteins, then add them as a complex.

A protein complex of translational regulators of GCN4 mRNA is the guanine nucleotide-exchange factor for translation initiation factor 2 in yeast.

Cigan AM, Bushman JL, Boal TR, Hinnebusch AG

In Saccharomyces cerevisiae, phosphorylation of the alpha subunit of translation initiation factor 2 (eIF-2) by protein kinase GCN2 stimulates translation of GCN4 mRNA. In mammalian cells, phosphorylation of eIF-2 alpha inhibits the activity of eIF-2B, the GDP-GTP exchange factor for eIF-2. We present biochemical evidence that five translational regulators of GCN4 encoded by GCD1, GCD2, GCD6, GCD7, and GCN3 are ... [more]

Affinity Capture-Western
Affinity Capture-Western

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.
