UniProt Comments
Metabolic-stress sensing protein kinase that phosphorylates the alpha subunit of eukaryotic translation initiation factor 2 eIF-2-alpha in response to low amino acid availability. Plays a role as an activator of the general amino acid control pathway required for adapatation to amino acid starvation. Converts phosphorylated eIF-2-alpha either to a competitive inhibitor of translation initiation, leading to a global protein synthesis repression, and thus to a reduced overall utilization of amino acids, or to a translational initiation activation of specific mRNAs, and hence allowing reprogramming of amino acid biosynthetic gene expression to alleviate nutrient depletion. Binds uncharged tRNAs.
