    Description: Variabilin, a novel inhibitor of human platelet aggregation, it is a potent RGD (Arg-Gly-Asp)-containing antagonist of the fibrinogen receptor glycoprotein IIb-IIIa (GPIIb-IIIa; αIIbβ3) and the vitronectin receptor αvβ3.Variabilin is also an antimicrobial furanosesterterpene. Variabilin is an inhibitor of human secretory and cytosolic phospholipase A2 (PLA2) activities that controls eicosanoid production in vitro and in vivo, inhibits neutrophil degranulation and superoxide generation in vitro and shows anti-inflammatory activity after topical or p.o. administration to mice.
    Targets: Phospholipase (e.g. PLA) | Immunology & Inflammation related
    In vitro:
    J. Biol. Chem., 1996, 271(30):17785-90.
    Variabilin, a Novel RGD-containing Antagonist of Glycoprotein IIb-IIIa and Platelet Aggregation Inhibitor from the Hard Tick Dermacentor variabilis*[Reference: WebLink]

    METHODS AND RESULTS:
    A novel inhibitor of human platelet aggregation, named variabilin, was isolated from salivary glands of the hard tick Dermacentor variabilis using a combination of gel filtration and high pressure liquid chromatography. Variabilin was a potent antagonist of the fibrinogen receptor glycoprotein IIb-IIIa (GPIIb-IIIa; αIIbβ3) and the vitronectin receptor αvβ3. Amino acid sequence analysis by Edman degradation revealed that it has 47 residues, with a molecular weight of 4968.5. Like many other naturally occurring antagonists of GPIIb-IIIa, variabilin contains the RGD (Arg-Gly-Asp) motif. However, unlike the RGD-containing antagonists of GPIIb-IIIa, the RGD sequence of variabilin is not positioned in a loop bracketed by cysteine residues.
    CONCLUSIONS:
    It has little sequence homology to the other known naturally occurring antagonists of GPIIb-IIIa, including the disintegrins from snakes, decorsin and ornatin from leeches, and disagregin from soft ticks. Variabilin is the first RGD-containing antagonist isolated from ticks.
