Fas ligand or FasL is a homotrimeric type II transmembrane protein that belongs to the tumor necrosis factor (TNF) family. It signals through trimerization of FasR, which spans the membrane of the target cell. This trimerization usually leads to apoptosis, or programmed cell death. Soluble Fas ligand is generated by cleaving membrane-bound FasL at a conserved cleavage site by the external matrix metalloproteinase MMP-7.
