What's a GeneRIF?

eEF1Bgamma co-immunoprecipitates with an essential component of ER-Golgi transport vesicles. Taken together, these results support a broader protein metabolism role for eEF1Bgamma.
Title: The eukaryotic translation elongation Factor 1Bgamma has a non-guanine nucleotide exchange factor role in protein metabolism.
The data obtained demonstrate involvement of the translation elongation factor eEF1B in modulating the functions of translation termination factors and suggest its possible role in GDP for GTP exchange on eRF3.
Title: Elongation factor eEF1B modulates functions of the release factors eRF1 and eRF3 and the efficiency of translation termination in yeast.
Coordination of eukaryotic translation elongation factor 1A (eEF1A) function in actin organization and translation elongation by the guanine nucleotide exchange factor eEF1Balpha.
Title: Coordination of eukaryotic translation elongation factor 1A (eEF1A) function in actin organization and translation elongation by the guanine nucleotide exchange factor eEF1Balpha.
Deletion of the two nonessential genes encoding eEF1Bgamma (TEF3 & TEF4) has no dramatic effects on total protein synthesis or translational fidelity. Instead, loss of each gene gives resistance to oxidative stress.
Title: The translation elongation factor eEF1B plays a role in the oxidative stress response pathway.
Mg2+ has a role in nucleotide exchange by eEF1B alpha and there is a catalytic function of Lys-205 in displacing Mg2+ from its binding site
Title: Mg2+ and a key lysine modulate exchange activity of eukaryotic translation elongation factor 1B alpha.
