CC -!- FUNCTION: mRNA cap-binding component of the eukaryotic translation
CC initiation factor 3 (eIF-3) complex, a complex required for several
CC steps in the initiation of protein synthesis of a specialized
CC repertoire of mRNAs. The eIF-3 complex associates with the 40S ribosome
CC and facilitates the recruitment of eIF-1, eIF-1A, eIF-2:GTP:methionyl-
CC tRNAi and eIF-5 to form the 43S pre-initiation complex (43S PIC). The
CC eIF-3 complex stimulates mRNA recruitment to the 43S PIC and scanning
CC of the mRNA for AUG recognition. The eIF-3 complex is also required for
CC disassembly and recycling of post-termination ribosomal complexes and
CC subsequently prevents premature joining of the 40S and 60S ribosomal
CC subunits prior to initiation. The eIF-3 complex specifically targets
CC and initiates translation of a subset of mRNAs involved in cell
CC proliferation, including cell cycling, differentiation and apoptosis,
CC and uses different modes of RNA stem-loop binding to exert either
CC translational activation or repression. In the eIF-3 complex, EIF3D
CC specifically recognizes and binds the 7-methylguanosine cap of a subset
CC of mRNAs. {ECO:0000255|HAMAP-Rule:MF_03003}.
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_03003}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03003}.
CC -!- DOMAIN: The RNA gate region regulates mRNA cap recognition to prevent
CC promiscuous mRNA-binding before assembly of eif3d into the full
CC eukaryotic translation initiation factor 3 (eIF-3) complex.
CC {ECO:0000255|HAMAP-Rule:MF_03003}.
CC -!- SIMILARITY: Belongs to the eIF-3 subunit D family. {ECO:0000255|HAMAP-
CC Rule:MF_03003}.
