The protein encoded by this gene acts at the level of translation initiation to downregulate protein synthesis in response to stress. The encoded protein is a kinase that can be inactivated by hemin. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]
Function
ATP binding; eukaryotic translation initiation factor 2alpha kinase activity; heme binding; protein homodimerization activity;
