Disease
[F13A_HUMAN] Defects in F13A1 are the cause of factor XIII subunit A deficiency (FA13AD) [MIM:613225]. FA13AD is an autosomal recessive disorder characterized by a life-long bleeding tendency, impaired wound healing and spontaneous abortion in affected women.[1]
Function
[F13A_HUMAN] Factor XIII is activated by thrombin and calcium ion to a transglutaminase that catalyzes the formation of gamma-glutamyl-epsilon-lysine cross-links between fibrin chains, thus stabilizing the fibrin clot. Also cross-link alpha-2-plasmin inhibitor, or fibronectin, to the alpha chains of fibrin.
Publication Abstract from PubMed
On active duty: The available drugs for cardiovascular diseases can promote blood clotting but can also lead to life-threatening bleeding episodes. A promising target for the development of safer alternatives is the transglutaminase Factor XIII (FXIII), the active structure of which is presented. The binding and coordination of three calcium ions induce major domain movements in the enzyme upon activation.
