Protein

Elongation factor 3A

Gene

YEF3

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Required for the ATP-dependent release of deacylated tRNA from the ribosomal E-site during protein biosynthesis. Stimulates the eEF1A-dependent binding of aminoacyl-tRNA to the ribosomal A-site, which has reduced affinity for tRNA as long as the E-site is occupied. Plays a role as a negative regulator of the GCN2 kinase activity; impairs GCN1-mediated GCN2 activation on ribosomes by reducing GCN1-ribosome affinity, and hence GCN2-mediated eIF-2-alpha phosphorylation in amino acid-starved or repleted cells (PubMed:22888004).3 Publications

Miscellaneous

Present with 870578 molecules/cell in log phase SD medium.1 Publication

Enzyme regulationi

Inhibited by the translational inhibitors neomycin and alpha-sarcin, which suppress the ATPase activity.1 Publication
