Overview

  • Product nameRFX5 Kit
  • Species reactivity
    Human RFX5 from a variety of fibroblast and B-cell lysates.
  • Product overview

    Anti-RFX5 (N-terminal specific) may react with unknown minor bands at 85 kDa and 55 kDa.

  • Tested applicationsSuitable for: ELISA, IP, WBmore details

Properties

  • FunctionActivates transcription from class II MHC promoters. Recognizes X-boxes. Mediates cooperative binding between RFX and NF-Y. RFX binds the X1 box of MHC-II promoters.
  • Tissue specificityUbiquitous.
  • Involvement in diseaseDefects in RFX5 are a cause of bare lymphocyte syndrome type 2 (BLS2) [MIM:209920]; also known as hereditary MHC class II deficiency or HLA class II-deficient combined immunodeficiency. BLS2 is a severe combined immunodeficiency disease with early onset. It is characterized by a profound defect in constitutive and interferon-gamma induced MHC II expression, absence of cellular and humoral T-cell response to antigen challenge, hypogammaglobulinemia and impaired antibody production. The consequence include extreme susceptibility to viral, bacterial and fungal infections.
  • Sequence similaritiesBelongs to the RFX family.
    Contains 1 RFX-type winged-helix DNA-binding domain.
  • DomainThe N-terminus is required for dimer formation, association with RFXANK and RFXAP, assembly of the RFX complex, and for binding of this complex to its X box target site in the MHC-II promoter. The C-terminus mediates cooperative binding between the RFX complex and NF-Y.
