thromboplastin

A Dictionary of Biology | 2004 | Copyright

thromboplastin (tissue factor; Factor III) A membrane glycoprotein expressed on the surface of damaged tissue cells that initiates the cascade of reactions leading to formation of a blood clot. It forms a complex with Factor VIIa in the presence of phospholipid and calcium ions; this complex converts Factor X to Xa, which in turn converts prothrombin to thrombin. See blood clotting.
