CC -!- FUNCTION: Component of the eukaryotic translation initiation factor 3
CC (eIF-3) complex, which is involved in protein synthesis of a
CC specialized repertoire of mRNAs and, together with other initiation
CC factors, stimulates binding of mRNA and methionyl-tRNAi to the 40S
CC ribosome. The eIF-3 complex specifically targets and initiates
CC translation of a subset of mRNAs involved in cell proliferation.
CC {ECO:0000255|HAMAP-Rule:MF_03008}.
CC -!- SUBUNIT: Component of the eukaryotic translation initiation factor 3
CC (eIF-3) complex. The eIF-3 complex interacts with pix.
CC {ECO:0000255|HAMAP-Rule:MF_03008}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03008}.
CC -!- SIMILARITY: Belongs to the eIF-3 subunit I family. {ECO:0000255|HAMAP-
CC Rule:MF_03008}.
