CC   -!- FUNCTION: Component of the eukaryotic translation initiation factor 3
CC       (eIF-3) complex, which is required for several steps in the initiation
CC       of protein synthesis. The eIF-3 complex associates with the 40S
CC       ribosome and facilitates the recruitment of eIF-1, eIF-1A, eIF-
CC       2:GTP:methionyl-tRNAi and eIF-5 to form the 43S pre-initiation complex
CC       (43S PIC). The eIF-3 complex stimulates mRNA recruitment to the 43S PIC
CC       and scanning of the mRNA for AUG recognition. The eIF-3 complex is also
CC       required for disassembly and recycling of post-termination ribosomal
CC       complexes and subsequently prevents premature joining of the 40S and
CC       60S ribosomal subunits prior to initiation. The eIF-3 complex
CC       specifically targets and initiates translation of a subset of mRNAs
CC       involved in cell proliferation, including cell cycling, differentiation
CC       and apoptosis, and uses different modes of RNA stem-loop binding to
CC       exert either translational activation or repression. This subunit binds
CC       directly within the mRNA entry channel of the 40S ribosome to the
CC       aminoacyl (A) site. It may regulate the interaction between the 43S PIC
CC       and mRNA. {ECO:0000255|HAMAP-Rule:MF_03009}.
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. The eIF-3 complex appears to include 3 stable modules: module A
CC       is composed of EIF3A, EIF3B, EIF3G and EIF3I; module B is composed of
CC       EIF3F, EIF3H, and EIF3M; and module C is composed of EIF3C, EIF3D,
CC       EIF3E, EIF3K and EIF3L. EIF3C of module C binds EIF3B of module A and
CC       EIF3H of module B, thereby linking the three modules. EIF3J is a labile
CC       subunit that binds to the eIF-3 complex via EIF3B. The eIF-3 complex
CC       interacts with RPS6KB1 under conditions of nutrient depletion.
CC       Mitogenic stimulation leads to binding and activation of a complex
CC       composed of MTOR and RPTOR, leading to phosphorylation and release of
CC       RPS6KB1 and binding of EIF4B to eIF-3. {ECO:0000255|HAMAP-
CC       Rule:MF_03009}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03009}.
CC   -!- PTM: Phosphorylated. Phosphorylation is enhanced upon serum
CC       stimulation. {ECO:0000255|HAMAP-Rule:MF_03009}.
CC   -!- SIMILARITY: Belongs to the eIF-3 subunit J family. {ECO:0000255|HAMAP-
CC       Rule:MF_03009}.
