Protein Tyrosine Phosphatase Genes Downregulated in Melanoma

Chemical rescue of protein tyrosine phosphatase activity.

We report that the activity of a rationally engineered protein tyrosine phosphatase (PTP) mutant can be fully rescued by the addition of the biarsenical fluorescein derivative FlAsH, a compound that does not affect the activity of wild-type PTPs.

PTPRA ( protein tyrosine phosphatase , receptor type , A )

Review on PTPRA, with data on DNA/RNA expression, on the protein encoded, and the functional importance of the gene.

Tripeptide inhibitors of Yersinia protein-tyrosine phosphatase.

The protein-tyrosine phosphatase (PTP) 'YopH' is a virulence factor of Yersinia pestis, the causative agent of plague. Potential use of Yersinia as a bioterrorism agent renders YopH inhibitors of therapeutic importance. Previously, we had examined the inhibitory potencies of a variety of phosphotyrosyl (pTyr) mimetics against the human PTP1B enzyme by displaying them in the EGFR-derived hexapep...
