Historical Perspective

Protein S was first discovered and purified in Seattle, Washington in 1979, and it was arbitrarily named protein S after the city it was discovered in. At the time, the function of this protein was still unknown; however, it was hypothesized that protein S plays a role in activating protein C. Protein S deficiency was first discovered in 1984 when two related individuals with recurrent thromboembolic events and normal coagulation tests were studied. These individuals were found to have diminished anticoagulation activity, and when purified human protein S was added to their plasma, effective anticoagulation was restored.
