1H/13C/15N triple-resonance experiments for structure determinaton of membrane proteins by oriented-sample NMR

Where the heart beats

In this issue of Structure, Reddy et al. present details about the structure, topology, and dynamics of the small membrane protein DWORF, a regulin that activates the Ca²⁺ pump SERCA. State-of-the art oriented solid-state NMR spectroscopy in combination with molecular dynamics simulations reveal the structure of this cardiac muscle protein.
