Conjugated compositions comprising a fragment of HIV-1 Vpr or a non-HIV-1 Vpr protein conjugated to a therapeutic compound and methods of using the same to deliver therapeutic compounds to a cell's nucleus or for the preparation of drug delivery particles are disclosed. Functional fragments of HIV-1 Vpr and functional non-HIV-1 Vpr proteins, and pharmaceutical compositions comprising the same are disclosed. Methods of inhibiting cell proliferation and methods of treating an individual who has a hyperproliferative disease are disclosed. Methods of identifying compounds that inhibit Vpr protein binding to the p6 domain of p55 or to p6 protein and kits for performing such methods are disclosed.

A method of constructing biologically active compounds which mimic the biological activity of the biologically active protein block the activity of the biologically active protein is disclosed. A method of identifying specific and discrete portions of pathogen antigens which either serve as epitopes for neutralizing antibodies or which are involved in pathogen binding to host cell receptors is disclosed. A method of constructing biologically active compounds which compete with cellular receptors for binding to either biologically active proteins or pathogen antigens is disclosed.

A method of identifying peptides which mimic biologically active proteins is disclosed. The method comprises the steps of making a recombinant antibody library from genetic material obtained from an animal which has been immunized against antibodies that bind to the biological active protein to the mimicked. Recombinant antibodies are screened to identify antibodies which compete with the biological active protein. Peptides which comprise the recombinant antibody's CDR sequences are synthesized. Synthetic peptides which mimic GM-CSF are also disclosed.
