CC   -!- FUNCTION: Tick salivary platelet aggregation inhibitor that plays an
CC       important part in the anti-hemostatic strategy of ticks. Inhibits
CC       platelet aggregation induced by ADP, thrombin and thromboxane A2
CC       (TXA2). Blocks platelet adhesion to soluble collagen (most probably
CC       through the binding to alpha-2/beta-1 integrin (ITGA2/ITGB1)) and binds
CC       to purified glycoprotein IIb/IIIa (ITGA2B/ITGB3) in a dose-dependent
CC       manner. In vivo, reduces thrombus weight effectively in a rat
CC       arteriovenous shunt model and inhibits thrombosis in a carrageenan-
CC       induced mouse tail thrombosis model. {ECO:0000250|UniProtKB:Q4PMW1}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:Q4PMW1}.
CC   -!- TISSUE SPECIFICITY: Expressed in salivary glands.
CC       {ECO:0000250|UniProtKB:Q4PMW1}.
CC   -!- PTM: Contains 3 disulfide bonds. {ECO:0000250|UniProtKB:Q4PMW1}.
CC   -!- SIMILARITY: Belongs to the ixodegrin family. {ECO:0000305}.
