    Snippet: Taking into consideration the fact that YopH has a similar amino-acid sequence in the active site as those for other PTPs [8] , including human ones, we compared the effect of ATA on human CD45 phosphatase. Protein tyrosine phosphatase CD45 is abundantly expressed in all non-nucleated haematopoietic cells and is critical for T-cell and B-cell functions. It dephosphorylates the Src kinases, therefore is important to immune-receptor modulated signa.....
    Document: Taking into consideration the fact that YopH has a similar amino-acid sequence in the active site as those for other PTPs [8] , including human ones, we compared the effect of ATA on human CD45 phosphatase. Protein tyrosine phosphatase CD45 is abundantly expressed in all non-nucleated haematopoietic cells and is critical for T-cell and B-cell functions. It dephosphorylates the Src kinases, therefore is important to immune-receptor modulated signaling. The inactivation of CD45 would lead to serious complications for the host immunity [21] . We found that ATA is more effective against YopH phosphatase than CD45.
