PLN is released as the zymogen plasminogen (PLG) which is converted to the active PLN by a variety of enzymes. PLN cleavage produces angiostatin. Microplasmin induces posterior vitreous detachment from the retina (PVD). Disease PLN mutations are associated with ligneous conjunctivitis and other disorders which lead to development of pseudo membranes on mucosal surfaces. Structural highlights PLN contains 7 domains which are: N-terminal, C-terminal serine protease catalytic domain and 5 kringle domains of ca. 80 residues. The kringle domain folds into a large loop containing 3 disulfide bonds, e.g. Kringle 4. The kringle domain is important in protein-protein interaction with blood coagulation factors..
