The function of Ensembl gene identifier ENSG00000125551 (PLGLB2, plasminogen like B2) is as follows. May bind noncovalently to lysine binding sites present in the kringle structures of plasminogen. This may interfere with the binding of fibrin or alpha-2-antiplasmin to plasminogen and may result in the localization of activity at sites necessary for extracellular matrix destruction.
