TWEAK Protein refers to the cytokine tumor necrosis factor-like weak inducer of apoptosis, belongs to tumor necrosis factor (TNF) superfamily. TWEAK protein binds to FN14 and TNRFSF12/APO3, is a weak inducer of apoptosis[1]. TWEAK does have pro-apoptotic activity for tumor cell, mediates NF-kappa-B activation, promotes angiogenesis and the proliferation of endothelial cells (ECs) [2]. TWEAK also increases IL-6 and IL-8 secretion, and could potentiate the pro-inflammatory activities of TNF and IL-1[3]. TWEAK protein is a type II transmembrane protein (M1-H249) with a transmembrane domain. TWEAK/TNFSF12 Protein, Rat (HEK293, Fc) is produced by HEK293 cells (R105-H249) with N-terminal rFc-tag.
