    摘要: A tissue plasminogen activator (t-PA) variant is prepared that has an amino acid deletion at positions 466 to 470 of the corresponding wild-type t-PA. This alteration renders the variant fibrin (and plasma clot) specific as compared to the corresponding wild-type t-PA. DNA sequences can be prepared that encode the variant, as well as expression vectors incorporating the DNA sequences, and host cells transformed with the expression vectors. The variant may be used in a pharmaceutical preparation to treat a vascular disease or condition or to prevent fibrin deposition or adhesion formation or reformation in mammals.
