hematopoietic system phenotype ( J:67798 )
N
• homozygotes displayed normal bleeding times
• at 8-12 weeks of age, homozygotes had normal platelet numbers in peripheral blood
• early events of platelet activation (e.g. shape change and granule release) and the initial rate of platelet aggregation appeared normal
• no differences were detected in the cleavage pattern and kinetics of calpain substrates
abnormal platelet physiology ( J:67798 )
• platelets showed impaired tyrosine phosphorylation of several proteins upon activation with either calcium ionophore or thrombin, including the beta3 subunit of alphaIIb-beta3 integrin (~70% reduction)
decreased platelet aggregation ( J:67798 )
• platelet aggregation was decreased by 50-60% in response to thrombin (10 nM), ADP (20 uM), collagen (20 ug/ml), and calcium ionophore A23187 (1.0 uM)
abnormal platelet dense granule physiology ( J:67798 )
• subtle differences were detected in the ATP secretion from dense granules upon thrombin and collagen activation; no differences were detected in the ADP- and calcium ionophore A23187-treated platelets

homeostasis/metabolism
abnormal blood coagulation ( J:67798 )
• platelets were defective in retracting clots, especially when clot formation was induced with 1.0 nM thrombin
abnormal platelet physiology ( J:67798 )
• platelets showed impaired tyrosine phosphorylation of several proteins upon activation with either calcium ionophore or thrombin, including the beta3 subunit of alphaIIb-beta3 integrin (~70% reduction)
