Gene: CIITA (class II major histocompatibility complex transactivator) Homo sapiens
Symbol: CIITA
Name: class II major histocompatibility complex transactivator
Description: Exhibits activating transcription factor binding activity; protein C-terminus binding activity; and transcription regulatory region DNA binding activity. Involved in regulation of macromolecule biosynthetic process; response to antibiotic; and response to interferon-gamma. Localizes to the PML body and cytosol. Implicated in Addison's disease; MHC class II deficiency; autoimmune hypersensitivity disease (multiple); myocardial infarction; and rheumatoid arthritis (multiple).
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: C2TA; CIITAIV; class II, major histocompatibility complex, transactivator; MHC class II transactivator; MHC class II transactivator type I; MHC class II transactivator type III; MHC2TA; NLR family, acid domain containing; NLRA; nucleotide-binding oligomerization domain, leucine rich repeat and acid domain containing
