NFX1 is a transcriptional repressor capable of binding to the conserved X box motif of HLA-DRA and other MHC class II genes in vitro. It may play a role in the inflammatory response, regulating its duration by limiting the period in which class II MHC molecules are induced by IFN gamma. The RING type zinc finger domain interacts with an ubiquitin conjugating enzyme (E2) and facilitates ubiquitination.

Transcriptional repressor NF-X1
亚基
Isoform 1 and isoform 3 interact with human papillomavirus (HPV) type-16 E6 oncoprotein. Isoform 1 interacts with PABPC1 and PABPC4.
亚细胞定位
Nucleus.
翻译后修饰
Isoform 3 is polyubiquitinated in the presence of HPV16 E6 protein; which leads to proteasomal degradation. Isoform 1 is not polyubiquitinated.
相似性
Belongs to the NFX1 family. Contains 8 NF-X1-type zinc fingers. Contains 1 R3H domain. Contains 1 RING-type zinc finger.
功能
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.
