Anti-magnesium-dependent phosphatase 1 antibodies enable researchers to detect and measure the magnesium-dependent phosphatase 1 antigen in biological samples. This target is a reported synonym of the MDP1 gene, which encodes magnesium dependent phosphatase 1. This protein is reported to be a magnesium-dependent phosphatase, which may act as a tyrosine phosphatase. The human version of magnesium-dependent phosphatase 1 has a canonical amino acid length of 176 residues and a protein mass of 20.1 kilodaltons, although 3 isoforms have been identified. magnesium-dependent phosphatase 1 is a member of the HAD-like hydrolase protein superfamily.
