A nucleic acid mol. (I) encoding a prepro protein which, in mature form, has the biological activity of mistletoe lectin dimer or a fragment of this prepro protein is new, provided that the nucleic acid mol. encoding the prepro protein has a defined sequence of 1923 bp given in the specification. Also claimed are: (1) a vector contg. (I); (2) a host transformed with the vector of (1); and (3) a polypeptide encoded by (I). |
