Protein tyrosine phosphatases (PTPs) play a critical role in regulating cellular functions by selectively dephosphorylating their substrates. Here we present 22 human PTP crystal structures that, together with prior structural knowledge, enable a comprehensive analysis of the classical PTP family. Despite their largely conserved fold, surface properties of(More)
Two members of the human aldo-keto reductase (AKR) superfamily participate in the biosynthesis of bile acids by catalyzing the NADP(H) dependent reduction of 3-keto groups (AKR1C4) and Delta4 double bonds (AKR1D1) of oxysterol precursors. Structure determination of human AKR1C4 and homology modelling of AKR1D1 followed by docking experiments were used to(More)
ABL2 (also known as ARG (ABL related gene)) is closely related to the well-studied Abelson kinase cABL. ABL2 is involved in human neoplastic diseases and is deregulated in solid tumors. Oncogenic gene translocations occur in acute leukemia. So far no structural information for ABL2 has been reported. To elucidate structural determinants for inhibitor(More)
