The kringle modules of apolipoprotein(a) [apo(a)] of lipoprotein(a), [Lp(a)] are highly homologous with kringle 4 of plasminogen (75-94%) and, like the latter are autonomous structural and functional units. Apo(a), contains 14-37 kringle 4 (KIV) repeats distributed into 10 classes (1-10)., Lp(a) binds lysine-Sepharose via a lysine binding site (LBS) located in, KIV-10 (88% homology with plasminogen K4). However, the W72R substitution, that occurs in rhesus monkeys and occasionally in humans leads to impaired, lysine binding capacity of KIV-10 and Lp(a). The foregoing has been, investigated by determining the structures of KIV-10/M66 (M66 variant) in, its unliganded and ligand [epsilon-aminocaproic acid (EACA)] bound modes, and the structure of recombinant KIV-10/M66R72 (the W72R mutant). ...

== Function ==
 +
[https://www.uniprot.org/uniprot/APOA_HUMAN APOA_HUMAN] Apo(a) is the main constituent of lipoprotein(a) (Lp(a)). It has serine proteinase activity and is able of autoproteolysis. Inhibits tissue-type plasminogen activator 1. Lp(a) may be a ligand for megalin/Gp 330.<ref>PMID:2531657</ref>
