Summary: Enables double-stranded RNA binding activity and protein kinase activity. Involved in several processes, including negative regulation of viral genome replication; regulation of hematopoietic stem cell differentiation; and regulation of intracellular signal transduction. Acts upstream of or within several processes, including endoplasmic reticulum unfolded protein response; protein phosphorylation; and translation. Predicted to be located in cytosol and perinuclear region of cytoplasm. Predicted to be active in cytoplasm and nucleus. Is expressed in several structures, including brain; genitourinary system; mandible condylar process; sensory organ; and skeletal musculature. Human ortholog(s) of this gene implicated in Alzheimer's disease; Huntington's disease; Parkinson's disease; dystonia 33; and hepatitis B. Orthologous to human EIF2AK2 (eukaryotic translation initiation factor 2 alpha kinase 2). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
