Target Information

This gene encodes coagulation factor XIII B subunit. Coagulation factor XIII is the last zymogen to become activated in the blood coagulation cascade. Plasma factor XIII is a heterotetramer composed of 2 A subunits and 2 B subunits. The A subunits have catalytic function, and the B subunits serve as plasma carrier molecules. Platelet factor XIII consists only of 2 A subunits, identical to those of plasma origin.

Upon activation by thrombin cleavage and in the presence of calcium ions, plasma factor XIII dissociates its B subunits and yields the active enzyme, factor XIIIa, identical to platelet factor XIII. This enzyme acts as a transglutaminase to catalyze gamma-glutamyl-epsilon-lysine crosslinking between fibrin molecules, stabilizing the fibrin clot.

Factor XIII deficiency is classified into:

• Type I deficiency: lack of both A and B subunits
• Type II deficiency: lack of the A subunit alone

These defects can lead to lifelong bleeding tendency, defective wound healing, and habitual abortion.
