Protein

Zinc metalloproteinase/disintegrin

Gene
N/A
Organism
Agkistrodon contortrix contortrix (Southern copperhead)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Snake venom metalloproteinase: impairs hemostasis in the envenomed animal (By similarity). This product has not been identified in the venom.By similarity
Disintegrin acostatin-beta: inhibits platelet aggregation in human platelet-rich plasma induced by ADP. Acts by inhibiting fibrinogen interaction with platelet receptors GPIIb/GPIIIa (ITGA2B/ITGB3).

Miscellaneous

The disintegrin belongs to the dimeric disintegrin subfamily.

Cofactori

Zn2+By similarityNote: Binds 1 zinc ion per subunit.By similarity
