The invention relates to plasminogen activators ob-tained by expression of fused cDNA encoding fragments of human tissue-type plasminogen activator (t-PA) and of human urokinase-type plasminogen activator (u-PA), by combining the fibrin-affinity of t-PA with the fibrin-specificity of u-PA in the single chain form (scu-PA) and/or with the enzymatic activity of u-PA having the two-chain form (tcu-PA). It is preferably a hybrid molecule obtained by fusion of at least a region part of the NH2-terminal region of t-PA to at least a part region of the COOH-terminal region of scu-PA, most preferably the NH2-terminal amino acids 1 to 263 of t-PA, fused to the COOH-terminal amino acids 144 to 411 of scu-PA. The invention relates further to a recombinant DNA molecule which yields said hybrid plasminogen activators; the respective mammalian expression vector containing said DNA sequence; a transfected mammalian cell line which com-prises said recombinant DNA molecule; and to the method for the preparation of plasminogen activators.
