NFX1 Antibody

NFX1 binds to the X-box motif of MHC class II genes and represses their expression. NFX1 may play an important role in regulating the duration of an inflammatory response by limiting the period in which MHC class II molecules are induced by interferon-gamma. Isoform 3 binds to the X-box motif of TERT promoter and represses its expression. Together with PABPC1 or PABPC4, isoform 1 acts as a coactivator for TERT expression. NFX1 mediates E2-dependent ubiquitination.MHC class II gene expression is controlled primarily at the transcriptional level by transcription factors that bind to the X and Y boxes, two highly conserved elements in the proximal promoter of MHC class II genes. The protein encoded by this gene is a transcriptional repressor capable of binding to the conserved X box motif of HLA-DRA and other MHC class II genes in vitro. The protein may play a role in regulating the duration of an inflammatory response by limiting the period in which class II MHC molecules are induced by IFN-gamma. Three alternative splice variants, each of which encodes a different isoform, have been identified.

For short periods of storage (days) store at 4˚ C. For longer periods of storage, store NFX1 antibody at -20˚ C. As with any antibody avoid repeat freeze-thaw cycles.

NFX1 antibody can be used for detection of NFX1 by ELISA at 1:62500. NFX1 antibody can be used for detection of NFX1 by western blot at 1 μ g/mL, and HRP conjugated secondary antibody should be diluted 1:50,000 - 100,000.
