Anti-ATPase secretory pathway Ca2+ transporting 2 antibodies are available from several suppliers. In humans, this protein is encoded by the gene ATP2C2. The protein may also be known as SPCA2, calcium-transporting ATPase type 2C member 2, and ATPase 2C2. The expected protein mass is 103.2 kDa, but there are 3 reported isoforms. Variants of this antigen may also be found in other species, including canine, porcine, monkey, mouse and rat.
