Tumor necrosis factor receptor superfamily member 12A (TNFRSF12A) is the receptor for TNFSD12/TWEAK and is the smallest member of the TNF receptor superfamily. It is composed of a signal peptide, an extracellular domain, a membrane-anchoring domain, and a cytoplasmic “death” domain, which can activate a cell’s apoptotic mechanisms. It also promotes endothelial cell proliferation and angiogenesis, and modulates cellular adhesion to matrix proteins. TNFRSF12A expression can be found in the spleen, thymus, small intestine, and colon, and can be activated by membrane-anchored or soluble versions of TWEAK.

Storage
The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity.
