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_03004}.
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:0000255|HAMAP-Rule:MF_03004}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03004}.
CC       Nucleus {ECO:0000255|HAMAP-Rule:MF_03004}.
CC   -!- SIMILARITY: Belongs to the eIF-3 subunit E family. {ECO:0000255|HAMAP-
CC       Rule:MF_03004}.
