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}.
