Fas配体（TNFSF6）与Fas抗原（TNFRSF6）的相互作用介导许多器官系统中的程序性细胞死亡，也称为凋亡该基因编码的蛋白与FAS抗原结合，通过FAS抗原启动细胞凋亡或增强细胞凋亡由该基因编码的蛋白启动凋亡需要泛素样结构域，而不是fas结合结构域。[由RefSeq提供，2008年7月]
Interaction of Fas ligand (TNFSF6) with the FAS antigen (TNFRSF6) mediates programmed cell death, also called apoptosis, in a number of organ systems. The protein encoded by this gene binds to FAS antigen and can initiate apoptosis or enhance apoptosis initiated through FAS antigen. Initiation of apoptosis by the protein encoded by this gene requires a ubiquitin-like domain but not the FAS-binding domain. [provided by RefSeq, Jul 2008]
