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}.
