Anti-SPCA2 antibodies enable researchers to detect and measure the SPCA2 antigen in biological samples. This target is a reported synonym of the ATP2C2 gene, which encodes ATPase secretory pathway Ca2+ transporting 2. This protein is known to function in the regulation of intracellular calcium and the transport of ions, among other biological roles. The human version of SPCA2 has a canonical amino acid length of 946 residues and a protein mass of 103.2 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the Golgi and cell membrane of cells and widely expressed in many tissue types. This target antigen may also be known as calcium-transporting ATPase type 2C member 2.
