Scientists are studying the structure and function of Receptor X, a single-polypeptide protein that is found in the membrane around certain types of cells. Receptor X contains no alpha-helices or beta sheets. A specific molecule outside the cells is recognized and bound by Receptor X. The binding of the molecule to Receptor X causes the cells to have a particular response.
