| Annotations for the interaction | figure legend:f5 sf3 comment:"\"To demonstrate that the direct interaction occurring between active catechins and STAT1 is one of the principal molecular mechanisms of STAT1 Tyr701 phosphorylation inhibition, a cell-free kinase in vitro assay was performed. Recombinant STAT1, pre-incubated with active catechins, were mixed with recombinant active JAK2. Western blot shows the ability of anti-STAT1 catechins to reduce, in a dose-dependent manner, in vitro STAT1 phosphorylation (Figure 5). In line with our hypothesis, we also demonstrated that the inactive compounds were not able to prevent STAT1 phosphorylation (data not shown).\"" comment:Finally, cell free JAK2-kinase assays support SPR and docking data, and confirm that the direct binding of active catechins with STAT1 protein is an important event to affect Tyr701 phosphorylation. Indeed, in vitro kinase assay data indicate that wtSTAT1-catechins pre-treatmentwas able to inhibit, in a dose dependent manner, STAT1 Tyr701 phosphorylation otherwise these effect was not observed with H568A-STAT1 protein curation depth:imex curation full coverage:Only protein-protein interactions |
