Summaries for RFXANK Gene

Entrez Gene Summary for RFXANK Gene

  • Major histocompatibility (MHC) class II molecules are transmembrane proteins that have a central role in development and control of the immune system. The protein encoded by this gene, along with regulatory factor X-associated protein and regulatory factor-5, forms a complex that binds to the X box motif of certain MHC class II gene promoters and activates their transcription. Once bound to the promoter, this complex associates with the non-DNA-binding factor MHC class II transactivator, which controls the cell type specificity and inducibility of MHC class II gene expression. This protein contains ankyrin repeats involved in protein-protein interactions. Mutations in this gene have been linked to bare lymphocyte syndrome type II, complementation group B. Multiple alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Jul 2013]

GeneCards Summary for RFXANK Gene

RFXANK (Regulatory Factor X-Associated Ankyrin-Containing Protein) is a Protein Coding gene. Diseases associated with RFXANK include bare lymphocyte syndrome, type ii, complementation group c and mhc class ii deficiency. Among its related pathways are EGFR1 Signaling Pathway and Tuberculosis. GO annotations related to this gene include sequence-specific DNA binding transcription factor activity and transcription cofactor activity. An important paralog of this gene is ANKRA2.

UniProtKB/Swiss-Prot for RFXANK Gene

  • Activates transcription from class II MHC promoters. Activation requires the activity of the MHC class II transactivator (MHC2TA). May regulate other genes in the cell. RFX binds the X1 box of MHC-II promoters. Isoform RFX-B-delta5 is not involved in the positive regulation of MHC class II genes

  • Bare lymphocyte syndrome 2 (BLS2) [MIM:209920]: 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. {ECO:0000269 PubMed:10072068, ECO:0000269 PubMed:10725724, ECO:0000269 PubMed:9806546}. Note=The disease is caused by mutations affecting the gene represented in this entry.
