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:0000255|HAMAP-Rule:MF_03001}.
CC -!- SUBUNIT: Component of the eukaryotic translation initiation factor 3
CC (eIF-3) complex. {ECO:0000255|HAMAP-Rule:MF_03001}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03001}.
CC -!- SIMILARITY: Belongs to the eIF-3 subunit B family. {ECO:0000255|HAMAP-
CC Rule:MF_03001}.
