cDNA sequence of human apolipoprotein(a) is homologous to plasminogen

Nature. 1987 Nov 12-18;330(6144):132-7. doi: 10.1038/330132a0.

Abstract

Lipoprotein(a) is an LDL-like lipoprotein whose concentration in plasma is correlated with atherosclerosis. The characteristic protein component of lipoprotein(a) is apolipoprotein(a) which is disulphide-linked to apolipoprotein B-100. Sequencing of cloned human apolipoprotein(a) complementary DNA shows that it is very similar to human plasminogen. It contains a serine protease domain and two types of plasminogen-like kringle domains, one of which is present in 37 copies.
