Involvement in diseasei

Bare lymphocyte syndrome 2 (BLS2)2 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA 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.

Interactioni

Subunit structurei

The RFX heterotetrameric complex consists of 2 molecules of RFX5 and one each of RFXAP and RFX-B/RFXANK; with each subunit representing a separate complementation group. RFX forms cooperative DNA binding complexes with X2BP and CBF/NF-Y. RFX associates with CIITA to form an active transcriptional complex.1 Publication
