TNFRSF1A (TNF RI) protein has a high ability to bind with tumor necrosis factor-alpha (TNF-α) . TNFRSF1A is a STAT3 target gene that regulates the NF-κB pathway. TNFRSF1A activate NF-kappaB, mediate apoptosis, and function as a regulator of inflammation. TNF RI/TNFRSF1A Protein, Mouse (HEK293, His) is expressed by HEK 293 cells and has a transmembrane region with a His tag at the C-terminus[1].
