Multiple in vivo phosphorylated tyrosine phosphatase SHP-2 engages binding to Grb2 via tyrosine 584.
SHP-2 (also named PTP1D, syp, or SH-PTP2) has been identified as a phosphotyrosine phosphatase comprising two src-homology-2 (SH2) domains. Upon growth factor stimulation, SHP-2 becomes tyrosine phosphorylated, thereby increasing its catalytic activity. Here, we identified SHP-2 to be phosphorylated on multiple tyrosine residues in response to different stimuli and unmasked the carboxyl-termina...
متن کاملTyrosine-Phosphorylated Bacterial Proteins
For over a century, since the discovery by Roux and Yersin that sterile culture supernatants of Corynebacterium diphtheriae contained a potent toxin able to reproduce the lesions caused by diphtheria (1), most pathogenic bacteria have been considered to be microorganisms able to intoxicate local and distant tissues by secreting toxins in the ex-tracellular medium. Recently, it has been shown th...
متن کاملp140/c-Abl that binds DNA is preferentially phosphorylated at tyrosine residues.
EP is a DNA element found in the enhancer and promoter regions of several cellular and viral genes. Previously, we have identified the DNA binding p140/c-Abl protein that specifically recognizes this element. Here we show that phosphorylation is essential for the p140/c-Abl DNA binding activity and for the formation of DNA-protein complexes. Furthermore, by 32P labeling of cells and protein pur...
متن کاملTyrosine phosphorylation of P160 BCR by P210 BCR-ABL.
It is well established that the chimeric BCR-ABL gene formed by joining parts of the BCR and ABL genes plays a key role in the pathogenesis of Philadelphia (Ph) chromosome-positive leukemias. We report that simultaneous expression of P210 BCR-ABL and P160 BCR in simian COS-1 cells yielded stable complexes of these two proteins, and induced phosphorylation of P160 BCR on tyrosine residues in viv...
متن کاملThe Grb2 binding site is required for the induction of chronic myeloid leukemia-like disease in mice by the Bcr/Abl tyrosine kinase.
The BCR/ABL oncogene results from a balanced translocation between chromosomes 9 and 22 and is found in patients with chronic myeloid leukemia (CML) and in some patients with acute B-lymphoid leukemia. The Bcr/Abl fusion protein is a constitutively active tyrosine kinase that stimulates several intracellular signaling pathways, including activation of Ras through direct binding of the SH2-conta...
