Structural study of any single-pass membrane protein is both an important and challenging task. In this report, we present the structure of a neurotrophin receptor-alike death-domain protein. The structure and dynamics of the protein was investigated by conventional nuclear magnetic resonance techniques in the solution of phospholipid bicelles. The receptor contains two folded regions-α-helical transmembrane domain and globular C-terminal death domain with more than 50% of the rest of backbone being disordered. This is the first structure of a full-length single-pass membrane receptor-alike protein solved by the single method.
