Apolipoprotein(a) inhibits the conversion of Glu-plasminogen to Lys-plasminogen on the surface of vascular endothelial and smooth muscle cells.

Lipoprotein(a) [Lp(a)] is an enigmatic lipoprotein which has been identified as a causal risk factor for coronary heart disease and calcific aortic valve disease. Lp(a) consists of a low-density lipoprotein (LDL) moiety covalently linked to the unique glycoprotein apolipoprotein(a) [apo(a)]. Apo(a) is homologous to the fibrinolytic zymogen plasminogen and thus may interfere with plasminogen activation.
