Summary: Enables RNA endonuclease activity; protein homodimerization activity; and protein serine/threonine kinase activity. Involved in intracellular signal transduction; positive regulation of macromolecule metabolic process; and protein autophosphorylation. Acts upstream of or within endoplasmic reticulum unfolded protein response. Located in endoplasmic reticulum membrane; mitochondrion; and nuclear inner membrane. Part of AIP1-IRE1 complex. Is expressed in several structures, including brain; connective tissue; hemolymphoid system gland; long bone; and tooth. Human ortholog(s) of this gene implicated in hepatocellular carcinoma. Orthologous to human ERN1 (endoplasmic reticulum to nucleus signaling 1). [provided by Alliance of Genome Resources, Dec 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.
