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_03010}.
CC   -!- SUBUNIT: Component of the eukaryotic translation initiation factor 3
CC       (eIF-3) complex. {ECO:0000255|HAMAP-Rule:MF_03010}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03010}.
CC   -!- SIMILARITY: Belongs to the eIF-3 subunit K family. {ECO:0000255|HAMAP-
CC       Rule:MF_03010}.
