这个基因是肿瘤坏死因子超家族的成员编码的跨膜蛋白的主要功能是通过与fas结合诱导细胞凋亡。Fas/FasLG信号通路是免疫系统调节的关键，包括T细胞的活化诱导的细胞死亡（AICD）和细胞毒性T淋巴细胞诱导的细胞死亡。它也与一些癌症的进展有关。该基因缺陷可能与系统性红斑狼疮（sle）有关。另外，已经描述了剪接转录变体。[由RefSeq提供，2014年11月]
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]
