Predicted to enable double-stranded RNA binding activity; eukaryotic translation initiation factor 2alpha kinase activity; and identical protein binding activity. Involved in several processes, including response to exogenous dsRNA; response to lipopolysaccharide; and response to vitamin E. Located in nucleus. Biomarker of pulmonary venoocclusive disease. Human ortholog(s) of this gene implicated in Alzheimer's disease; Huntington's disease; Parkinson's disease; and hepatitis B. Orthologous to human EIF2AK2 (eukaryotic translation initiation factor 2 alpha kinase 2). [provided by Alliance of Genome Resources, Apr 2022]
