Abstract
The subject invention provides purified polypeptides encoded by naturally-occurring wild-type platelet glycoprotein Ib alpha having a mutation which renders the polypeptide less reactive with von Willebrand factor. Preferably, the mutation is in the leucine rich region of GPIb.alpha., such as the substitution of phenylalanine for leucine at residue 57. DNA encoding the mutant polypeptides, as well as expression systems for the production of the mutant polypeptides, are also provided. Methods and compositions using the mutant polypeptides and DNA oligomers complementary to the mutant polypeptides are further provided.
