Summary
This gene is a member of the tumor necrosis factor superfamily. The primary function of the encoded transmembrane protein is the induction of apoptosis triggered by binding to FAS. The FAS/FASLG signaling pathway is essential for immune system regulation, including activation-induced cell death (AICD) of T cells and cytotoxic T lymphocyte induced cell death. It has also been implicated in the progression of several cancers. Defects in this gene may be related to some cases of systemic lupus erythematosus (SLE). Alternatively spliced transcript variants have been described. [provided by RefSeq, Nov 2014]

nef Upregulation of Fas ligand by HIV-1 Nef is mediated through a direct interaction of Nef with the T cell Receptor zeta chain and binding of Nef to the Nef-associated kinase (NAK/p62) PubMed
nef HIV-1 Nef sensitizes CD4+ T lymphoid cells to apoptosis by upregulating the expression of both Fas and Fas ligand, an effect that requires the PxxP motif (amino acids 72-75) in the core region of Nef PubMed
nef The PxxP domain of HIV-1 Nef is required for upregulation of Fas ligand transcription and p38 MAPK activation by Nef PubMed
nef Experiments using a dominant-negative isoform of p38 MAPK, p38 siRNA, and inhibitors of p38 activation indicate that p38 is required for HIV-1 Nef-induced Fas ligand upregulation PubMed

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
