Anti-RPTPmu antibodies enable researchers to detect and measure the RPTPmu antigen in biological samples. This target is a reported synonym of the PTPRM gene, which encodes protein tyrosine phosphatase receptor type M. This protein is known to function in cell adhesion and the regulation of angiogenesis, among other biological roles. The human version of RPTPmu has a canonical amino acid length of 1452 residues and a protein mass of 163.7 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells and widely expressed in many tissue types. Other names for this target antigen include PTPRL1 and RPTPM.
