Introduction | Protein tyrosine phosphatase mitochondrial 1 (PTPMT1) is a broadly expressed PTP membrane protein with high expression levels in pancreatic beta cells. The PTPMT1 protein is completely restricted to the matrix face of the inner membrane of the mitochondrion. PTPMT1 is responsible for dephosphorylating mitochondrial proteins and thus has a major role in the production of ATP and secretion of insulin. PTPMT1 exhibits a specific preference for the lipid signaling molecule phosphatidylinositol 5-phosphate as substrate. |
Synonyms | Protein-tyrosine phosphatase mitochondrial 1, PTEN-like phosphatase, Phosphoinositide lipid phosphatase, PTPMT1, MOSP, PLIP, DUSP23, PNAS-129. |
Source | Escherichia Coli. |
Physical Appearance | Sterile Filtered colorless solution. |
Formulation | The PTPMT1 solution (1mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 10% glycerol, 1mM DTT and 0.15M NaCl. |
