NEDD4 ubiquitylation activity is restrained by an evolutionarily conserved allosteric auto-inhibition mechanism: ubiquitylation of a conserved lysine on the HECT domain α1-helix promotes NEDD4 oligomerization (trimerization) that renders the ligase inactive. Arginine substitution of the ubiquitylated lysine impairs this inactivation and causes unrestrained FGFR1 ubiquitylation and constitutive IKS channel downregulation. |
