CC -!- FUNCTION: Component of the protein complex eIF4F, which is involved in
CC the recognition of the mRNA cap, ATP-dependent unwinding of 5'-terminal
CC secondary structure and recruitment of mRNA to the ribosome (By
CC similarity). Recognizes and binds the 7-methylguanosine-containing mRNA
CC cap during an early step in the initiation of protein synthesis and
CC facilitates ribosome binding by inducing the unwinding of the mRNAs
CC secondary structures (By similarity). {ECO:0000250|UniProtKB:P48599}.
CC -!- SUBUNIT: EIF4F is a multi-subunit complex, the composition of which
CC varies with external and internal environmental conditions
CC (PubMed:16343979). It is composed of at least EIF4A, EIF4E and EIF4G
CC (PubMed:16343979). EIF4E is also known to interact with other partners
CC (PubMed:16343979). In higher plants two isoforms of EIF4F have been
CC identified, named isoform EIF4F and isoform EIF(iso)4F
CC (PubMed:16343979). Isoform EIF4F has subunits p220 and p26, whereas
CC isoform EIF(iso)4F has subunits p82 and p28 (PubMed:16343979).
CC {ECO:0000269|PubMed:16343979}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:K0P2S0}. Cytoplasm
CC {ECO:0000250|UniProtKB:K0P2S0}.
CC -!- PTM: According to the redox status, the Cys-138-Cys-176 disulfide
CC bridge may have a role in regulating protein function by affecting its
CC ability to bind capped mRNA. {ECO:0000250|UniProtKB:P29557}.
CC -!- SIMILARITY: Belongs to the eukaryotic initiation factor 4E family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAG51741.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
