Anti-Pez antibodies enable researchers to detect and measure the Pez antigen in biological samples. This target is a reported synonym of the PTPN14 gene, which encodes protein tyrosine phosphatase non-receptor type 14. This protein is known to function in the regulation of cell proliferation and protein dephosphorylation, among other biological roles. The human version of Pez has a canonical amino acid length of 1187 residues and a protein mass of 135.3 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells. Other names for this target antigen include CATLPH and PTP36.
