Summary
Predicted to enable DNA-binding transcription factor binding activity and transcription cis-regulatory region binding activity. Involved in several processes, including cellular response to electrical stimulus; cellular response to exogenous dsRNA; and regulation of transcription by RNA polymerase II. Located in cell surface. Used to study periapical periodontitis. Human ortholog(s) of this gene implicated in Addison's disease; MHC class II deficiency; autoimmune disease (multiple); and myocardial infarction. Orthologous to human CIITA (class II major histocompatibility complex transactivator). [provided by Alliance of Genome Resources, Jun 2025]

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.
