Disintegrin VLO5A

Gene
N/A
Organism
Macrovipera lebetina obtusa (Levant blunt-nosed viper) (Vipera lebetina obtusa)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Poor inhibitor of platelet aggregation. The disintegrin inhibits the adhesion of the alpha-4/beta-1 (ITGA4/ITGB1) integrin to VCAM-1. Inhibition on alpha-IIb/beta-3 (ITGA2B/ITGB3) is low.1 Publication

Miscellaneous

Does not inhibit alpha-1/beta-1 (ITGA1/ITGB1), alpha-2/beta-1 (ITGA2/ITGB1) and alpha-6/beta-1 (ITGA6/ITGB1).1 Publication
The disintegrin belongs to the dimeric disintegrin subfamily.
