Background Information

Protein Tyrosine Phosphatase localized to the Mitochondrial 1 (PTPMT1) is a highly conserved, dual-specific phosphatase that resides on the matrix-facing side of the inner mitochondrial membrane (IMM). PTPMT1 is a mitochondrial phosphatase and a vital regulator of mitochondrial activities. Current work points to roles for PTPMT1 in the regulation of mitochondrial respiration, dynamics, and ultrastructure through the modulation of pyruvate importation, the tuning of TCA cycle activity, and the synthesis of cardiolipin. PTPMT1 is highly expressed in pancreatic b cells, whose mitochondria have the important function of coupling glucose metabolism to the secretion of insulin.
