This paper describes the isolation, cloning, and molecular characterization of a receptor molecule for calcium ions located on the outer surface of certain types of cells. The reason it has received so much attention from the scientific community is that "this was the first evidence that extracellular calcium ions [Ca$2+$ ]\; could\; have\; direct\; effects\; on\; certain\; cells\; via\; a\; membrane-bound\; receptor,"\; declares\; Edward\; Brown,\; a\; professor\; of\; medicine\; in\; the\; endocrine-hypertension\; division\; of\; the\; department\; of\; medicine\; at\; Brigham\; and\; Women\text{'}s\; Hospital\; and\; Harvard\; Medical\; School.$$
