Background: F13A1

Coagulation Factor XIIIa1 (F13a1) is a member of the transglutaminase family which includes F13A1 and TGM1-7 (1). F13 in the plasma is a tetrameric complex composed of two alpha (A) and two beta (B) chains where the A subunit is a transglutaminase zymogen and the B subunit is an inhibitory glycoprotein with no enzymatic function (2).  Activation by thrombin and calcium ions results in the formation of the catalytically active transglutaminase F13a composed of an alpha chain homodimer capable of forming gamma-glutamyl-epsilon-lysine cross-links. The 83 kDa F13a monomer has an N-terminal activation peptide and a beta sandwich preceding the catalytic core with catalytic triad active site and two C-terminal beta barrels (3). The active homodimer is intracellular in platelets, megakaryocytes, monocytes and macrophages. The primary physiological outcome of the catalytic activity of F13a is cross-linking of fibrin and anti-plasmin to stabilize the fibrin clot (4,5). However, in addition to cross-linking fibrin, F13a is capable of cross-linking many substrates involved in complement activation, coagulation, inflammatory and immune responses and extracellular matrix organization (6). Cross-linking of key substrates by F13a has been directly shown to play a role in in atherosclerosis (7), wound healing (8), angiogenesis (9,10), maintaining pregnancy (11), ECM deposition, osteoblast differentiation and bone remodeling (12), and immune defense (13). F13A has also been detected as a marker in acute promyelocytic leukemia (APL)(14) and expression is considered of value for diagnosis and prognosis for leukemia-associated immunophenotype. Congenital deficiency results in bleeding manifestations including intercranial hemorrhage (15), poor wound healing (17), and spontaneous abortions (17) that can be treated with F13 (18).
