NFX1 NFX2

Transcriptional repressor NF-X1 (Nuclear transcription factor, X box-binding protein 1)

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. [provided by RefSeq, Jul 2008],

Domain:The RING-type zinc finger domain interacts with an ubiquitin-conjugating enzyme (E2) and facilitates ubiquitination.,Function:Binds to the X-box motif of MHC class II genes and represses their expression. 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. Mediates E2-dependent ubiquitination.,induction:By interferon gamma.,PTM:Isoform 3 is polyubiquitinated in the presence of HPV16 E6 protein; which leads to proteasomal degradation. Isoform 1 is not polyubiquitinated.,similarity:Belongs to the NFX1 family.,similarity:Contains 1 R3H domain.,similarity:Contains 1 RING-type zinc finger.,similarity:Contains 8 NF-X1-type zinc fingers.,subunit:Isoform 1 and isoform 3 interact with human papillomavirus (HPV) type-16 E6 oncoprotein. Isoform 1 interacts with PABPC1 and PABPC4.,
