Anti-PMR1 antibodies enable researchers to detect and measure the PMR1 antigen in biological samples. This target is a reported synonym of the ATP2C1 gene, which encodes ATPase secretory pathway Ca2+ transporting 1. This protein is known to function in cytoskeleton organization and the transport of ions, among other biological roles. The human version of PMR1 has a canonical amino acid length of 919 residues and a protein mass of 100.6 kilodaltons, although 9 isoforms have been identified. It is reported to be localized in the Golgi of cells and widely expressed in many tissue types. PMR1 is a member of the Cation transport ATPase (P-type) (TC 3.A.3) protein family.
