CC -!- FUNCTION: Component of the eukaryotic translation initiation factor 3
CC (eIF-3) complex, which is involved in protein synthesis and, together
CC with other initiation factors, stimulates binding of mRNA and
CC methionyl-tRNAi to the 40S ribosome. {ECO:0000256|PIRNR:PIRNR036424}.
CC -!- FUNCTION: RNA-binding component of the eukaryotic translation
CC initiation factor 3 (eIF-3) complex, which is involved in protein
CC synthesis of a specialized repertoire of mRNAs and, together with other
CC initiation factors, stimulates binding of mRNA and methionyl-tRNAi to
CC the 40S ribosome. The eIF-3 complex specifically targets and initiates
CC translation of a subset of mRNAs involved in cell proliferation.
CC {ECO:0000256|HAMAP-Rule:MF_03001}.
CC -!- SUBUNIT: Component of the eukaryotic translation initiation factor 3
CC (eIF-3) complex, which is composed of 13 subunits: EIF3A, EIF3B, EIF3C,
CC EIF3D, EIF3E, EIF3F, EIF3G, EIF3H, EIF3I, EIF3J, EIF3K, EIF3L and
CC EIF3M. {ECO:0000256|HAMAP-Rule:MF_03001}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_03001,
CC ECO:0000256|PIRNR:PIRNR036424}.
CC -!- SIMILARITY: Belongs to the eIF-3 subunit B family. {ECO:0000256|HAMAP-
CC Rule:MF_03001, ECO:0000256|PIRNR:PIRNR036424}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:KYO30705.1}.
