    • Function

      Component 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.
    • Sequence similarities

      Belongs to the eIF-3 subunit B family.
      Contains 1 RRM (RNA recognition motif) domain.
      Contains 5 WD repeats.
    • Domain

      The RRM domain mediates interaction with EIF3J.
    • Post-translational

      Phosphorylated. Phosphorylation is enhanced upon serum stimulation.
    • Cellular localization
