Anti-RFX1 Antibody

RFX1 is a member of the regulatory factor X protein family, which are transcription factors that contain a highly-conserved winged helix DNA binding domain and the D region found in the C-terminal part of these proteins which facilitates dimerization (1,2) . RFX1 is structurally related to regulatory factors X2, X3, X4, and X5 (3) . RFX1 is a regulatory factor essential for MHC class II genes expression and can bind to an inverted repeat that is required for expression of hepatitis B virus genes (4) . Recent study identifies RFX1 may play a tumor suppressor role in HCC as autophagy mediator (5) .

RFX1 antibody was raised against an 18 amino acid peptide near the carboxy terminus of human RFX1. The immunogen is located within the last 50 amino acids of RFX1.

Regulatory factor essential for MHC class II genes expression. Binds to the X boxes of MHC class II genes. Also binds to an inverted repeat (ENH1) required for hepatitis B virus genes expression and to the most upstream element (alpha) of the RPL30 promoter.
