Three new variants in the plasminogen system

H Nishimukai, Y Kera, K Sakata

    Human Heredity
    |January 1, 1982
    PubMed
    Summary

    Three novel plasminogen system phenotypes (PLG 3-1, PLG 1-M, PLG 1-C) were identified in healthy Japanese individuals. The PLG 3 component appears to be genetically determined, suggesting a new PLG3 allele may exist.

    Area of Science:

    • Biochemistry
    • Human Genetics
    • Molecular Biology

    Background:

    • The plasminogen system is crucial for fibrinolysis.
    • Genetic variations in the plasminogen system can impact physiological processes.
    • Previous studies have identified various plasminogen phenotypes.

    Purpose of the Study:

    • To identify and characterize new phenotypes of the human plasminogen system.
    • To investigate the genetic basis of the identified plasminogen variants.

    Main Methods:

    • Agarose gel isoelectric focusing was employed to separate plasminogen variants.
    • Immunofixation was used to identify specific plasminogen components.
    • Caseinolysis assays were performed to assess functional activity.

    Main Results:

    • Three novel plasminogen phenotypes, designated PLG 3-1, PLG 1-M, and PLG 1-C, were discovered in sera from healthy Japanese individuals.
    • The PLG 3 component was found to be genetically determined.
    • Evidence suggests the existence of an additional PLG3 allele.

    Conclusions:

    • The human plasminogen system exhibits greater phenotypic diversity than previously recognized.
    • Genetic factors play a significant role in determining plasminogen phenotypes.
    • The identification of new phenotypes and potential alleles advances our understanding of plasminogen system genetics.
