The PDGF beta receptor is negatively regulated by protein tyrosine phosphatases (PTPs).|In summary, our findings identify TC-PTP as a previously unrecognized negative regulator of PDGF beta receptor signaling and support the general notion that PTPs display site selectivity in their action on tyrosine kinase receptors.The fact that two of the investigated PDGF β receptor sites, Y1021 and Y771, displayed a larger increase in phosphorylation than Y579 and Y751 in TC-PTP ko MEFs indicated that these two sites are preferred substrates for TC-PTP. |

Upon ligand binding, IL-2R , IL-6R or LeptinR , IFN-_R , IFN-_R and PRLR or growth hormone (GH) receptor associated JAKs become activated. These JAKs mediate phosphorylation of specific tyrosine residues and recruit STATs. Activated STATs are released from the receptor and translocate to the nucleus. PTP1B dephosphorylates JAK2, TYK2 and STAT5 . The 45-kDa form of TC-PTP was shown to dephosphorylate JAK1 and JAK3 as well as STAT1, STAT3 and STAT5. |

These results indicate that TC45 recognizes not only selected substrates in a cellular context but also specific sites within substrates and thus may regulate discrete signaling events. |

Stat1 becomes tyrosine phosphorylated and translocates into the nucleus, where it binds to dna to activate transcription. The activity of stat1 is dependent on tyrosine phosphorylation, and its inactivation in the nucleus is accomplished by a previously unknown protein tyrosine phosphatase (ptp). We have now purified a stat1 ptp activity from hela cell nuclear extract and identified it as tc45, the nuclear isoform of the t-cell ptp (tc-ptp). Tc45 can dephosphorylate stat1 both in vitro and in vivo. |

Upon interferon (IFN) stimulation, Stat1 becomes tyrosine phosphorylated and translocates into the nucleus, where it binds to DNA to activate transcription. The activity of Stat1 is dependent on tyrosine phosphorylation, and its inactivation in the nucleus is accomplished by a previously unknown protein tyrosine phosphatase (PTP). We have now purified a Stat1 PTP activity from HeLa cell nuclear extract and identified it as TC45, the nuclear isoform of the T-cell PTP (TC-PTP). |

Upon ligand binding, IL-2R , IL-6R or LeptinR , IFN-_R , IFN-_R and PRLR or growth hormone (GH) receptor associated JAKs become activated. These JAKs mediate phosphorylation of specific tyrosine residues and recruit STATs. Activated STATs are released from the receptor and translocate to the nucleus. PTP1B dephosphorylates JAK2, TYK2 and STAT5 . The 45-kDa form of TC-PTP was shown to dephosphorylate JAK1 and JAK3 as well as STAT1, STAT3 and STAT5. |

We show that a TCPTP substrate-trapping mutant interacts with VEGFR2. Moreover, TCPTP dephosphorylates VEGFR2 in a phosphosite-specific manner, inhibits its kinase activity and prevents its internalization from the cell surface. |The autophosphorylation sites Tyr1054/1059 and Tyr1214 were dephosphorylated by TCPTP (Fig. 4B). Tyr996, the functional significance of which is currently uncertain (Olsson et al., 2006), was a TCPTP target as well. |

Tc45 dephosphorylated delta egfr in u87mg glioblastoma cells and inhibited mitogen-activated protein kinase erk2 and phosphatidylinositol 3-kinase signaling. In contrast, the substrate-trapping tc45-d182a mutant, which is capable of forming stable complexes with tc45 substrates, suppressed the activation of erk2 but not phosphatidylinositol 3-kinase. The activation results in reduced egfr phosphorylation after egf stimulation. Introduction of the alpha(1) cytoplasmic domain peptide into cells induces phosphatase activation and inhibits egf-induced cell proliferation and anchorage-independent growth of malignant cells. |

We have documented that a cellular protein that binds the immunosuppressant drug fk506, termed the fk506-binding protein (fkbp52), interacts with the single-stranded d sequence within the aav inverted terminal repeats, inhibits viral second-strand dna synthesis, and consequently limits high-efficiency transgene expression. Deliberate overexpression of the murine wild-type (wt) tc-ptp gene, but not that of a cysteine-to-serine (c-s) mutant, caused tyrosine dephosphorylation of fkbp52, leading to efficient viral second-strand dna synthesis and resulting in a significant increase in aav-mediated transduction efficiency in hela cells in vitro. |
