Has a significant function in hemostasis as one of the primary elements of blood clots. In addition, functions during the early phases of wound repair to stabilize the lesion and guide cell migration during re- epithelialization.

Was originally thought to be essential for platelet aggregation, based on in vitro studies using anticoagulated blood. However, subsequent studies have demonstrated it is not absolutely required for thrombus formation in vivo.
