FlyBase Gene Report: Dmel\eIF3i

CYTOPLASMIC TRANSLATION INITIATION FACTORS -: Cytoplasmic (or eukaryotic) translation initiation factors function in the initiation stage of ribosome-mediated translation in the cytoplasm. (Adapted from FBrf0233552 and PMID:20094052).

Protein Function (UniProtKB)

Component of the eukaryotic translation initiation factor 3 (eIF-3) complex, which is involved in protein synthesis of a specialized repertoire of mRNAs and, together with other initiation factors, stimulates binding of mRNA and methionyl-tRNAi to the 40S ribosome. The eIF-3 complex specifically targets and initiates translation of a subset of mRNAs involved in cell proliferation.
