WebMar 13, 2003 · The function of the protein tyrosine phosphatase SHP-1 in cancer SHP-1, an SH2 domain-containing protein tyrosine phosphatase, is primarily expressed in hematopoietic cells and behaves as a key regulator controlling intracellular phosphotyrosine levels in lymphocytes. WebProtein tyrosine phosphatases(PTPs) are essential regulators of signal transduction pathways, and control, together with protein tyrosine kinases (PTKs), the reversible phosphorylation of tyrosine residues. The human genome contains 107 PTPs grouped into four distinct families [1]. Class I cysteine-based PTPs constitute the largest family.
