Apoprotein(a)

**Definition:** A large and highly glycosylated protein constituent of LIPOPROTEIN (A). It has very little affinity for lipids but forms disulfide-linkage to APOLIPOPROTEIN B-100. Apoprotein(a) has SERINE PROTEINASE activity and can be of varying sizes from 400- to 800-kDa. It is homologous to PLASMINOGEN and is known to modulate THROMBOSIS and FIBRINOLYSIS.
