eIF4G1 is a component of the multi-subunit eukaryotic translation initiation factor 4F, which facilitates recruitment of the mRNA to the ribosome, a rate-limiting step during translation initiation. This C-terminal domain, whose structure resembles that of a set of concatenated HEAT repeats, has been associated with binding to/recruiting the kinase Mnk1, which phosphorylates eIF4E. Length = 134
>gnl|CDD|214705 smart00515, eIF5C, Domain at the C-termini of GCD6, eIF-2B epsilon, eIF-4 gamma and eIF-5
eIF2B is a heteropentameric complex which functions as a guanine nucleotide exchange factor in the recycling of eIF-2 during the initiation of translation in eukaryotes. The epsilon and gamma subunits are sequence similar and both are essential in yeast. Epsilon appears to be the catalytically active subunit, with gamma enhancing its activity. The C-terminal domain of the eIF2B epsilon subunit contains bipartite motifs rich in acidic and aromatic residues, which are responsible for the interaction with eIF2. The structure of the domain resembles that of a set of concatenated HEAT repeats. Length = 169
eIF5 functions as a GTPase acceleration protein (GAP), as well as a GDP dissociation inhibitor (GDI) during translational initiation in eukaryotes. The structure of this C-terminal domain resembles that of a set of concatenated HEAT repeats. Length = 157

The W2 domain has a globular fold and is exclusively composed out of alpha-helices [, , ]. The structure can be divided into a structural C-terminal core onto which the two N-terminal helices are attached. The core contains two aromatic/acidic residue-rich regions (AA boxes), which are important for mediating protein-protein interactions. For example, the W2 domain of H. sapiens eIF5 binds eIF2-beta, eIF3 and eIF1 [], and therefore plays an important role in multifactor complex assembly. The entry covers the entire W2 domain.; GO: 0005488 binding; PDB: 3D3M_A 3L6A_A 1PAQ_A 2FUL_D 2IU1_A 1UG3_B 3JUI_A.
