A quaternary tetramer assembly inhibits the deubiquitinating activity of USP25
Abstract
USP25 is a deubiquitinating enzyme and a positive regulator of Wnt/β-catenin signaling. Here the authors present the crystal structure of USP25 in a tetrameric inactive state and their biochemical and kinetic assays support an USP25 autoinhibitory mechanism that is mediated through a dimer to tetramerization transition.
