PROTEIN
PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • a protein-protein interaction region with five ankirin repeats
  • an ankyrin repeat domain
  • mono polymer heteromer , trimer
    HOMOLOGY
    interspecies homolog to murine Rfxank
    homolog to C.elegans c06a12.3
    intraspecies paralog to ANKRA2
    Homologene
    FAMILY RFX family of DNA binding protein
    CATEGORY immunity/defense , regulatory , transcription factor
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,cytoplasm
    intracellular,nucleus,chromatin/chromosome
    basic FUNCTION
  • transactivating DNA binding regulator, involved in MHC class II expression
  • playing a role in facilitating promoter occupation in the context of chromatin
  • targets of class IIa HDACs playing a role in regulating MHCII expression
  • positive regulator of major histocompatibility complex II (MHC II) gene expression
  • DNA binding of RFX5 is inhibited by domains flanking its DNA binding domain, and both RFXAP and RFXANK are required to overcome the inhibition of both domains
  • CELLULAR PROCESS nucleotide, genomic integrity
    nucleotide, transcription, regulation
    PHYSIOLOGICAL PROCESS
    text humoral defense mechanism
    PATHWAY
    metabolism
    signaling
    a component
  • subunit of the multimeric phosphoprotein complex RFX, containing RFX5, RFXANK, RFXAP
  • forms the heterotrimeric RFX complex together with RFX5 and RFXAP, all are required for expression of MHCII genes
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • RFX5 and RFXAP
  • interacting with HDAC4 through its ankyrin repeat domain
  • HDAC4 and HDAC5 interact with the ankyrin repeats of ANKRA2 and RFXANK and, through association with RFXANK, repress MHC II promoter activation
