Tumor necrosis factor ligand superfamily member 12 (Tweak)
TWEAK is a cell surface-associated type II transmembrane protein, but a smaller, biologically active form can also be shed into the extracellular milieu. There is one receptor currently known to bind TWEAK with physiological affinity, and it is a type I transmembrane protein that is referred to in the literature as either TWEAK receptor (Tweak R) or fibroblast growth factor - inducible 14 (Fn14), which signals via recruitment of several different TNFR-associated factors. TWEAK has multiple biological activities, including stimulation of cell growth and angiogenesis, induction of inflammatory cytokines, and under some experimental conditions, stimulation of apoptosis.
