Summary: Enables several functions, including AP-1 adaptor complex binding activity; AP-2 adaptor complex binding activity; and double-stranded RNA binding activity. Involved in RNA catabolic process and RNA transport. Acts upstream of or within several processes, including regulation of insulin secretion involved in cellular response to glucose stimulus; type B pancreatic cell development; and type B pancreatic cell proliferation. Located in lysosomal membrane and plasma membrane. Is expressed in several structures, including inner ear; submandibular gland primordium; and vibrissa. Used to study metabolic dysfunction-associated steatotic liver disease. Orthologous to human SIDT2 (SID1 transmembrane family member 2). [provided by Alliance of Genome Resources, Dec 2024]

SIDT2, is required to transport internalized extracellular dsRNA from endocytic compartments into the cytoplasm for immune activation. Sidt2-deficient mice exposed to extracellular dsRNA, encephalomyocarditis virus (EMCV), and herpes simplex virus 1 (HSV-1) show impaired production of antiviral cytokines and-in the case of EMCV and HSV-1-reduced survival.

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.
