Lee, Kong-Ju; Kyounggi-do, Republic of Korea | | Summary: | This invention describes recombinant shLkn-1 characterized by enhanced biological activity. The invention relates to a truncated variant of the C6 ?-chemokine leukotactin-1 polypeptide consisting of the amino acid sequence of SEQ ID NO:2, as well as a process for preparing a recombinant shLkn-1 employing the expression vector and a pharmaceutical application of the protein. Further disclosed are methods by which shLkn-1 is generated by the missing 26 amino acid residues from the amino terminus of Lkn-1 to contain 66 amino acids. Claims of the invention describe recombinant shLkn-1 as inhibiting colony formation and cell proliferation in vivo, therefore suggesting it as a potential drug for antibody production such as in the treatment of HIV-1 infection, the protection of bone marrow stem cells during chemotherapy or radiotherapy, and in the inhibition of leukemia. | | Abstract: | 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.
