[[http://www.uniprot.org/uniprot/EIF3I_RABIT EIF3I_RABIT]] 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.[HAMAP-Rule:MF_03008] [[http://www.uniprot.org/uniprot/G1TN72_RABIT G1TN72_RABIT]] May play a role during erythropoiesis through regulation of transcription factor DDIT3 (By similarity).[HAMAP-Rule:MF_03122] [[http://www.uniprot.org/uniprot/EIF3G_HUMAN EIF3G_HUMAN]] Component of the eukaryotic translation initiation factor 3 (eIF-3) complex, which is required for several steps in the initiation of protein synthesis.
