  • FunctionEssential for transcriptional activity of the HLA class II promoter; activation is via the proximal promoter. No DNA binding of in vitro translated CIITA was detected. May act in a coactivator-like fashion through protein-protein interactions by contacting factors binding to the proximal MHC class II promoter, to elements of the transcription machinery, or both. Alternatively it may activate HLA class II transcription by modifying proteins that bind to the MHC class II promoter. Also mediates enhanced MHC class I transcription; the promoter element requirements for CIITA-mediated transcription are distinct from those of constitutive MHC class I transcription, and CIITA can functionally replace TAF1 at these genes. Exhibits intrinsic GTP-stimulated acetyltransferase activity. Exhibits serine/threonine protein kinase activity: can phosphorylate the TFIID component TAF7, the RAP74 subunit of the general transcription factor TFIIF, histone H2B at 'Ser-37' and other histones (in vitro).
  • Involvement in diseaseBare lymphocyte syndrome 2
  • Sequence similaritiesContains 4 LRR (leucine-rich) repeats.
    Contains 1 NACHT domain.
  • DomainThe acetyltransferase domain is necessary for activation of both class I and class II transcription.
    The GTP-binding motif doesn't confer GTPase activity but promotes nuclear localization.
  • Post-translational
    Autophosphorylated, affecting interaction with TAF7.
  • Cellular localizationNucleus. Nucleus, PML body. Recruited to PML body by PML.
