Functioni

Catalytic subunit of the guanine nucleotide exchange factor (GEF) (eEF1B subcomplex) of the eukaryotic elongation factor 1 complex (eEF1). Stimulates the exchange of GDP for GTP on elongation factor 1A (eEF1A), probably by displacing GDP from the nucleotide binding pocket in eEF1A. The 30-fold higher concentration of GTP compared to GDP in cells favors the formation of eEF1A-GTP, which rapidly forms a ternary complex with aminoacyl-tRNA that in turn displaces eEF1B from the complex.1 Publication

Interactioni

Subunit structurei

The eukaryotic elongation factor 1 complex (eEF1) is probably a heterohexamer. Two trimeric complexes, each composed of eEF1A (TEF1 or TEF2), eEF1Balpha (EFB1) and eEF1Bgamma (CAM1 or TEF4), are probably dimerized via the eF1Bgamma subunits. eEF1Balpha interacts directly with eEF1A. eEF1Balpha and eEF1Bgamma form the eEF1B subcomplex with the GEF activity.2 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
