Coagulation Factor XIII A Chain (FXIIIa)

Target
FXIIIa
Molecular classification
Enzyme, Transglutaminase
01

Overview

Factor XIIIa is the active form of coagulation factor XIII, a transglutaminase enzyme crucial for the final stages of blood clotting. It catalyzes the formation of covalent cross-links between fibrin molecules, stabilizing blood clots and protecting them from premature breakdown. It plays roles in wound healing, tissue repair, angiogenesis, and other intracellular processes. Deficiency leads to severe bleeding diathesis.
