ABSTRACT:
An apoptosis inducing agent which comprises a protein as being Vpr protein encoded by vpr gene of HIV-1 wherein 15 amino acid residues from the C-terminal are deleted, and an apoptosis inducing gene encoding said protein. The agent induces apoptosis of cells and therefore useful as a medicament for treatment of a cancer or AIDS.
