| 摘要 |
The present invention relates to a polypeptide having preferably antitumoral and/or immunomodulating cytokine properties, which can be activated by processing in vivo comprising a central region with specific biological activity. At its C-terminus said region has a region with a processing unit and an inhibitor domain, while at the N-terminus of the central region, there is a region that selectively recognizes a macromolecule on a cell surface or a component of the extracellular matrix.
