Coagulation Factor XIII A Subunit (FXIII-A)

Target
FXIII-A
Molecular classification
Enzyme, Transglutaminase
01

Overview

Coagulation factor XIII A subunit (FXIII-A) is a crucial enzyme in the blood coagulation cascade, responsible for stabilizing fibrin clots. It is a transglutaminase that catalyzes the formation of covalent cross-links between glutamine and lysine residues in fibrin molecules, increasing clot strength, rigidity, and resistance to fibrinolysis. Deficiency leads to bleeding diathesis.
