  • FunctionComponent of the eukaryotic translation initiation factor 3 (eIF-3) complex, which is required for several steps in the initiation of protein synthesis. The eIF-3 complex associates with the 40S ribosome and facilitates the recruitment of eIF-1, eIF-1A, eIF-2:GTP:methionyl-tRNAi and eIF-5 to form the 43S preinitiation complex (43S PIC). The eIF-3 complex stimulates mRNA recruitment to the 43S PIC and scanning of the mRNA for AUG recognition. The eIF-3 complex is also required for disassembly and recycling of post-termination ribosomal complexes and subsequently prevents premature joining of the 40S and 60S ribosomal subunits prior to initiation. This subunit can bind 18S rRNA.
  • Sequence similaritiesBelongs to the eIF-3 subunit G family.
    Contains 1 RRM (RNA recognition motif) domain.
  • Post-translational
    Phosphorylated. Phosphorylation is enhanced upon serum stimulation.
  • Cellular localizationCytoplasm. Nucleus. Cytoplasm > perinuclear region. Colocalizes with AIFM1 in the nucleus and perinuclear region.
