Research Backgrounds


Catalyzes the exchange of eukaryotic initiation factor 2-bound GDP for GTP.


Phosphorylated at Ser-544 by DYRK2; this is required for subsequent phosphorylation by GSK3B (By similarity). Phosphorylated on serine and threonine residues by GSK3B; phosphorylation inhibits its function.

Polyubiquitinated, probably by NEDD4.

Subunit Structure:

Complex of five different subunits; alpha, beta, gamma, delta and epsilon. Interacts with RGS2.


Belongs to the eIF-2B gamma/epsilon subunits family.
