Figure 3.Binding of 14-3-3 and Trx to ASK1 is part of the inhibitory ASK1-signalosome complex.Assembly of the inhibitory ASK1-signalosome involves the binding of ASK1 to 14-3-3 [56]. Using anti-ASK1 for co-immunoprecipitation analyses we demonstrated (A, C) 14-3-3 and (B, D) Trx are complexed with ASK1. Furthermore, the data show that the ASK1-Trx-14-3-3 complex, a characteristic of the inhibitory ASK1-signalosome, is significantly elevated in the Klotho overexpressing model. (E) Treatment of the liver extracts with the thiol-reacting reagent shows a higher level of reduced Trx in the Klotho overexpressing liver.
