Beschreibung
Zusammenfassung:	The present invention relates to a variant of Lkn-1(shLkn-1) with enhanced biological activity, which is a truncated form of Lkn-1, a process for preparing a recombinant shLkn-1 by employing expression vector therefor and pharmaceutical application of the said protein. shLkn-1 is generated by missing 26 amino acid residues from the amino terminus of Lkn-1 to contain 66 amino acids. Recombinant shLkn-1 inhibits colony formation and cell proliferation in vivo, which suggests that it can be used as a potential drug for the antibody production, the treatment during HIV-1 infection, the protection of bone marrow stem cells during chemotherapy or radiotherapy, and the inhibition of leukemia.
