Most of our knowledge on protein tyrosine phosphatases (PTPs) is derived from human pathologies and mouse knockout models. These models largely correlate well with human disease phenotypes, but can be ambiguous due to compensatory mechanisms introduced by paralogous genes. Here we present the analysis of the PTP complement of the fruit fly and the complementary view that PTP studies in Drosophila...
A complex network of signalling events coordinate the differentiation, activation and maintenance of T lymphocytes. Tyrosine phosphorylation and dephosphorylation by protein tyrosine kinases and protein tyrosine phosphatases (PTPs) respectively, are critical for the activation and propagation of these signalling cascades. Intriguingly, the removal of tyrosyl phosphate moieties from phosphorylated...
