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. CC {ECO:0000255|HAMAP-Rule:MF_03005}. CC -!- FUNCTION: Deubiquitinates activated NOTCH1, promoting its nuclear CC import, thereby acting as a positive regulator of Notch signaling. CC {ECO:0000255|HAMAP-Rule:MF_03005}. CC -!- CATALYTIC ACTIVITY: CC Reaction=Thiol-dependent hydrolysis of ester, thioester, amide, peptide CC and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76- CC residue protein attached to proteins as an intracellular targeting CC signal).; EC=3.4.19.12; 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. Interacts with RNF139; the CC interaction leads to protein translation inhibitions in a CC ubiquitination-dependent manner. Interacts with DTX1, the interaction CC is required for deubiquitinating activity towards NOTCH1 (By CC similarity). {ECO:0000255|HAMAP-Rule:MF_03005}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03005}. CC -!- DOMAIN: The MPN domain mediates deubiquitinating activity. CC {ECO:0000250}. CC -!- PTM: Phosphorylation is enhanced upon serum stimulation. Phosphorylated CC during apoptosis by caspase-processed CDK11 (By similarity). CC {ECO:0000250}. CC -!- SIMILARITY: Belongs to the eIF-3 subunit F family. {ECO:0000255|HAMAP- CC Rule:MF_03005}.
