Tight binding of the phosphorylated alpha subunit of initiation factor 2 (eIF2alpha) to the regulatory subunits of guanine nucleotide exchange factor eIF2B is required for inhibition of translation initiation.

Krishnamoorthy T, Pavitt GD, Zhang F, Dever TE, Hinnebusch AG

Translation initiation factor 2 (eIF2) is a heterotrimeric protein that transfers methionyl-initiator tRNA(Met) to the small ribosomal subunit in a ternary complex with GTP. The eIF2 phosphorylated on serine 51 of its alpha subunit [eIF2(alphaP)] acts as competitive inhibitor of its guanine nucleotide exchange factor, eIF2B, impairing formation of the ternary complex and thereby inhibiting translation initiation. eIF2B is comprised ...

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.
