Anti-NSP2 antibodies enable researchers to detect and measure the NSP2 antigen in biological samples. This target is a reported synonym of the RTN2 gene, which encodes reticulon 2. This protein is known to function in carbohydrate metabolism and homeostasis, among other biological roles. The human version of NSP2 has a canonical amino acid length of 545 residues and a protein mass of 59.3 kilodaltons. It is reported to be notably expressed in the smooth muscle, skeletal muscle, and breast.
