General annotation (Comments)

Function

Component of the protein complex eIF4F, which is involved in the recognition of the mRNA cap, ATP-dependent unwinding of 5'-terminal secondary structure and recruitment of mRNA to the ribosome By similarity.

Subunit structure

eIF4F is a multi-subunit complex, the composition of which varies with external and internal environmental conditions. It is composed of at least EIF4A, EIF4E and EIF4G1/EIF4G3. Interacts with eIF3, mutually exclusive with EIF4A1 or EIFA2, EIF4E and through its N-terminus with PAPBC1. Interacts through its C-terminus with the serine/threonine kinases MKNK1, and with MKNK2. Appears to act as a scaffold protein, holding these enzymes in place to phosphorylate EIF4E. Non-phosphorylated EIF4EBP1 competes with EIF4G1/EIF4G3 to interact with EIF4E; insulin stimulated MAP-kinase (MAPK1 and MAPK3) phosphorylation of EIF4EBP1 causes dissociation of the complex allowing EIF4G1/EIF4G3 to bind and consequent initiation of translation. Interacts with CIRBP and MIF4GD. Interacts with RBM4 By similarity. Interacts with EIF4E3. Ref.3

Post-translational modification

Phosphorylated at multiple sites in vivo. Phosphorylation at Ser-1187 by PRKCA induces binding to MKNK1 By similarity.

Sequence similarities

Belongs to the eukaryotic initiation factor 4G family.

Contains 1 MI domain.

Contains 1 MIF4G domain.

Contains 1 W2 domain.
