Thromboplastin, also known as Tissue Factor (TF), is a protein involved in the blood clotting process. Some synonyms for thromboplastin include Coagulation Factor III, Platelet Tissue Factor, and Factor III. These terms refer to the same protein and can be used interchangeably in scientific literature. In addition, TF may also be referred to as Thrombokinase, as it converts prothrombin into thrombin, a key step in the coagulation cascade. Understanding the terminology associated with thromboplastin is important for researchers, clinicians, and students studying the physiology of blood clotting and its complications.
