PTP Inhibitor III

PTP inhibitor III is a cell-permeable compound that inhibits a broad-range of PTPs (protein tyrosine phosphatases). PTPs help balance the activation of signaling proteins in vascular cells and keep the cells functioning in a normal state. The compound binds with a higher affinity to the catalytic domain of the SH2 domain-containing phosphatase SHP-1 than the PTP I inhibitor.
