Abstract: The present invention provides improved tPA variants having significantly reduced susceptibility to inhibition and increased affinity for platelet integrin as compared with the wild-type tPA. The present invention also provides compositions comprising the tPA variants and polynucleotides, vectors, and host cells for producing the same as well as methods of using these tPA variants to treat disease conditions, e.g., thrombotic disorders.
