    Summary
    Predicted to enable eukaryotic translation initiation factor 2alpha kinase activity. Acts upstream of or within response to endoplasmic reticulum stress and response to hypoxia. Predicted to be located in endoplasmic reticulum and membrane. Predicted to be active in cytoplasm and nucleus. Is expressed in brain; liver; and male organism. Human ortholog(s) of this gene implicated in Wolcott-Rallison syndrome and type 1 diabetes mellitus. Orthologous to human EIF2AK3 (eukaryotic translation initiation factor 2 alpha kinase 3).
