ZNRF2 is released from membranes by growth factors and, together with ZNRF1, regulates the Na+/K+ATPase.

Abstract excerpt

Here, we describe a phosphorylation-based reverse myristoyl switch for mammalian ZNRF2, and show that this E3 ubiquitin ligase and its sister protein ZNRF1 regulate the Na(+)/K(+) pump (Na(+)/K(+)ATPase). N-myristoylation localizes ZNRF1 and ZNRF2 to intracellular membranes and enhances their activity. However, when ZNRF2 is phosphorylated in response to agonists including insulin and growth factors, it binds to...
