SHP-1 dephosphorylates TonEBP/OREBP at a known regulatory site, Y143, both in vivo and in vitro. It inhibits TonEBP/OREBP by both reducing TonEBP/OREBP nuclear localization, which is Y143 dependent, and by lowering high NaCl-induced TonEBP/OREBP transactivating activity |

Caspase-8 is tyrosine-phosphorylated in freshly isolated neutrophils but spontaneously dephosphorylates in culture, in association with the progression of constitutive apoptosis. Phosphorylation of caspase-8 on Tyr-310 facilitates its interaction with the Src-homology domain 2 containing tyrosine phosphatase-1 (SHP-1) and enables SHP-1 to dephosphorylate caspase-8, permitting apoptosis to proceed. The non-receptor tyrosine kinase, Lyn, can phosphorylate caspase-8 on Tyr-397 and Tyr-465, rendering it resistant to activational cleavage and inhibiting apoptosis. Exposure to lipopolysaccharide reduces SHP-1 activity and binding to caspase-8, caspase-8 activity, and rates of spontaneous apoptosis. |

To determine whether the COOH-terminal or other phosphotyrosine residues within Src are subject to dephosphorylation by SHP-1, the effects of this phosphatase on Src tyrosine phosphorylation were initially examined using CNBr cleavage analysis. As illustrated in Fig.1 A, CNBr treatment of 32P-labeled human Src has been shown previously to yield phosphorylated cleavage fragments of about 31, 9.7, and 4.7 kDa, which, respectively, contain the Src NH2-terminal region encompassing the major sites for serine phosphorylation on Src, Ser-12 and Ser-17 (31-kDa fragment), the inhibitory tyrosine phosphorylation site, Tyr-530 (4.7-kDa fragment), and a key site for autophosphorylation on activated Src, Tyr-419 [} These observations, together with the finding of reduced Src activity in HEY cells expressing a dominant negative form of SHP-1, provide compelling evidence that SHP-1 functions include the positive regulation of Src activation. |

Furthermore, a small but reproducible growth/survival advantage was observed in both TF-1 and TF-1/ITD cells when SHP-1 expression was knocked down by RNAi. Taken together, these data provide the first evidence that suppression of SHP-1 by FLT3/ITD signaling may be another mechanism contributing to the transformation by FLT3/ITD mutations |

Our work clearly identifies cd72 as both an shp-1 binding protein (figure 1,figure 2) and a direct substrate for shp-1 in vivo (figure 3). As tyrosine phosphorylation of cd72 strongly correlates with the ability of the bcr to deliver growth-inhibitory/apoptosis-inducing signals (figure 4), our results suggest that shp-1-catalyzed dephosphorylation of cd72 may antagonize these signals. |

Tyrosine phosphorylation of SPAP2a by c-Src and in vitro. Tyrosine-phosphorylated SPAP2 is specifically associated with SH2 domain-containing tyrosine kinases Syk and Zap70 and SH2 domain-containing tyrosine phosphatases SHP-1 and SHP-2. Site-specific mutagenesis studies revealed that tyrosyl residues 650 and 662 embedded in the ITIMs are responsible for the binding of Syk and Zap70 while tyrosyl residues 692 and 722 embedded in the ITIMs are involved in interactions with SHP-1 and SHP-2. |
