Function
function
Snake venom metalloproteinase
Impairs hemostasis in the envenomed animal.
Disintegrin trigramin-alpha
Inhibits platelet aggregation induced by ADP, thrombin, platelet-activating factor and collagen. Acts by inhibiting fibrinogen interaction with platelet receptors GPIIb/GPIIIa (ITGA2B/ITGB3).
Miscellaneous
The disintegrin belongs to the medium disintegrin subfamily.
Cofactor
Note: Binds 1 zinc ion per subunit.
