[[http://www.uniprot.org/uniprot/PLMN_HUMAN PLMN_HUMAN]] Defects in PLG are the cause of plasminogen deficiency (PLGD) [MIM:[http://omim.org/entry/217090 217090]]. PLGD is characterized by decreased serum plasminogen activity. Two forms of the disorder are distinguished: type 1 deficiency is additionally characterized by decreased plasminogen antigen levels and clinical symptoms, whereas type 2 deficiency, also known as dysplasminogenemia, is characterized by normal, or slightly reduced antigen levels, and absence of clinical manifestations. Plasminogen deficiency type 1 results in markedly impaired extracellular fibrinolysis and chronic mucosal pseudomembranous lesions due to subepithelial fibrin deposition and inflammation. The most common clinical manifestation of type 1 deficiency is ligneous conjunctivitis in which pseudomembranes formation on the palpebral surfaces of the eye progresses to white, yellow-white, or red thick masses with a wood-like consistency that replace the normal mucosa.<ref>PMID:1986355</ref><ref>PMID:8392398</ref><ref>PMID:6216475</ref><ref>PMID:6238949</ref><ref>PMID:1427790</ref><ref>PMID:9242524</ref><ref>PMID:9858247</ref><ref>PMID:10233898</ref> | |||

[[http://www.uniprot.org/uniprot/COLY_YERPE COLY_YERPE]] Seems to play an essential role in plague transmission by mediating flea blockage in a temperature-dependent fashion. Fibrinolytic activity prevails at 37 degrees Celsius whereas coagulase expression predominates at lower temperatures (<30 degrees Celsius). Activates plasminogen by cleaving it. [[http://www.uniprot.org/uniprot/PLMN_HUMAN PLMN_HUMAN]] Plasmin dissolves the fibrin of blood clots and acts as a proteolytic factor in a variety of other processes including embryonic development, tissue remodeling, tumor invasion, and inflammation. In ovulation, weakens the walls of the Graafian follicle. It activates the urokinase-type plasminogen activator, collagenases and several complement zymogens, such as C1 and C5. Cleavage of fibronectin and laminin leads to cell detachment and apoptosis. Also cleaves fibrin, thrombospondin and von Willebrand factor. Its role in tissue remodeling and tumor invasion may be modulated by CSPG4.
