Anti-Npal2 antibodies enable researchers to detect and measure the Npal2 antigen in biological samples. This target is a reported synonym of the NIPAL2 gene, which encodes NIPA like domain containing 2. This protein is known to function in the transport of ions, among other biological roles. The human version of Npal2 has a canonical amino acid length of 383 residues and a protein mass of 42.2 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the membrane of cells. Npal2 is a member of the NIPA protein family.
