Anti-GAMMASNAP antibodies enable researchers to detect and measure the GAMMASNAP antigen in biological samples. This target is a reported synonym of the NAPG gene, which encodes NSF attachment protein gamma. This protein is known to function in intracellular protein transport and protein stabilization, among other biological roles. The human version of GAMMASNAP has a canonical amino acid length of 312 residues and a protein mass of 34.7 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the Golgi and membrane of cells and widely expressed in many tissue types. This target antigen may also be known as gamma-soluble NSF attachment protein.
