Abstract Apolipoprotein(a) [apo(a)] is the distinctive glycoprotein of lipoprotein Lp(a), which is disulfide linked to the apo B100 of a low density lipoprotein particle. Apo(a) possesses a high degree of sequence homology with plasminogen, the precursor of plasmin, a fibrinolytic and pericellular proteolytic enzyme. Apo(a) exists in several isoforms defined by a variable number of copies of plasminogenlike kringle 4 and single copies of kringle 5, and the protease region including the backbone…

Chemical Modification Induced by Glycation Increased Lysine Binding Site Activity of Human Serum Lipoprotein (a)

It is suggested that nonenzymatic glycation of Lp(a) may contribute to premature atherogenesis of patients with diabetes mellitus by increasing its Lysine binding site activity and diverting lipoprotein catabolism from non-athero genic to atherogenic pathways.

It is shown that sPmel17 consists of 2 fragments linked by disulfide bonds and that the shedding is inhibited at low temperature but not by metalloproteinase inhibitors, and that treatment with a phorbol ester or a calmodulin inhibitor induces Pmel17 shedding.

Characterization of the I4399M variant of apolipoprotein(a): implications for altered prothrombotic properties of lipoprotein(a)

Recombinant I4399M apo(a) altered clot structure to accelerate coagulation/delay fibrinolysis and evidence was found for increased solvent exposure and oxidation of Met residue.

Lipoprotein(a): A missing culprit in the management of athero‐thrombosis?

The patho‐physiological mechanisms by which Lp(a) may increase athero‐thrombosis and an overview on the therapeutic modalities to interfere with Lp (a) are summarized.

Differential density lipoprotein profiling for the characterization of Lipoprotein(a)

The objective of the present study was to develop a rapid method for the separation, purification, density measurement, and characterization of Lp(a) from serum using a procedure that is isoform independent, and the objective was met by linking ultracentrifugation with affinity separations for the specific separation of L p( a) from other lipoproteins.

Relation of Apolipoprotein(a) Size to Alzheimer’s Disease and Vascular Dementia

It is demonstrated that possession of at least one LMW apo(a) isoform is significantly associated with dementia and specifically offer new evidence of a strong association between the lipoprotein system and post-stroke dementia.

Expression of Biologically Active Kringle 5 Domain of Human Plasminogen in Escherichia coli

The recombinant kringle 5, with a yield of 10.5 mg/L culture, displayed apparent inhibition of endothelial cell proliferation in a dose‐dependent manner with ED50 about 20 nM.

Lipoprotein(a) as a cardiovascular risk factor.

The measurement of Lp(a) may be of value in individuals with an increased risk of cardiovascular disease, particularly in patients with high low-density lipoprotein cholesterol plasma levels, since a high Lp (a) concentration in such subjects further increases the risk of coronary heart disease.

The Repeat Domain of the Melanosomal Matrix Protein PMEL17/GP100 Is Required for the Formation of Organellar Fibers*

It is concluded that the RPT domain is essential for its function in generating the fibrillar matrix of melanosomes and that the luminal domain is necessary for its correct processing and trafficking to those organelles.

Expression of Kringle 5 Domain of Human Plasminogen in Pichia pastoris

The human kringle 5 encoding gene was cloned into secretory plasmid pPIC9K and then integrated into Pichia pastoris genome for expression and it showed promise in anti-angiogenic therapy.



Partial amino acid sequence of apolipoprotein(a) shows that it is homologous to plasminogen.

Using a plasmin-specific assay, no proteolytic activity could be demonstrated for lipoprotein(a) particles and results suggest that apo (a) contains kringle-like domains and an inactive protease domain.

Comparison of ligand-binding sites of modeled apo[a] kringle-like sequences in human lipoprotein[a].

Human lipoprotein[a] is a highly glycosylated, hydrophilic apoprotein that somewhat resembles plasminogen by containing an extended kringle domain and a carboxyl-terminal serine protease domain that appears to have structurally similar lysine-binding sites, but with differences that may influence ligand-polypeptide specificity.

The solution phase interaction between apolipoprotein(a) and plasminogen inhibits the binding of plasminogen to a plasmin-modified fibrinogen surface.

It is determined that r-apo(a) and plasminogen bind to distinct sites on plAsmin-modified fibrinogen with the concentration of plasmineogen binding sites exceeding the concentrationof r-apo(a), thus contributing to the atherothrombotic risk associated with this lipoprotein.

Apolipoprotein(a) and plasminogen interactions with fibrin: a study with recombinant apolipoprotein(a) and isolated plasminogen fragments.

Comparative fibrin binding studies using a recombinant form of apo(a), a glycoprotein absent from LDL which has a high degree of homology with plasminogen, suggest that r-apo(a) binds to both the intrachain lysines of intact fibr in and the carboxy-terminal lysine of degraded fibrIn.

Lipoprotein(a), fibrin binding, and plasminogen activation.

It is demonstrated that, like plasminogen, Lp(a) binds to fibrin, and it is suggested that Lp (a) influences the fibrinolytic system and probably does so by virtue of thefibrin binding properties conferred by the kringle repeats of apo(a).

Recombinant kringle IV-10 modules of human apolipoprotein(a): structure, ligand binding modes, and biological relevance.

The KIV-10/T66/EACA molecular structures are highly isostructural, indicating that the LBS of the kringles is preformed anticipating ligand binding, and loss of binding ability is the result of steric blockage of theLBS by R72 physically occupying part of the site.

A structural assessment of the apo[a] protein of human lipoprotein[a]

The analysis suggests that apo[a] kringle‐type 10 has a high probability of binding to lysine in the same way as PGK4, and an alternative site for the proteolytic activation of human apo,[a] is proposed.

Structural relationship of an apolipoprotein (a) phenotype (570 kDa) to plasminogen: homologous kringle domains are linked by carbohydrate-rich regions.

At least six allelic forms of apolipoprotein(a), differing in molecular mass, could be detected by immunoblot analysis. One of these phenotypes with a molecular mass of 570 kDa has been investigated.
