 AB    It has been demonstrated previously that molecular decoys of the
       acetylcholine receptor have therapeutic efficacy as antitoxins
       [Gershoni, J. and Aronheim, A. (1988) Proc. Natl Acad. Sci. USA, 85,
       4087-4089], but surely a most challenging goal is to apply this approach
       towards the development of antiviral drugs. As viruses present multiple
       copies of their envelope proteins, it was proposed that polyvalent
       decoys could be advantageous. Here we report the design and expression
       of recombinant linear polymers of the HIV gp120-binding domains which
       are situated within the T-cell membrane protein CD4. Whereas the
       production of linear concatemers of CD4 variable domains is feasible, a
       number of conformational constraints must be considered when designing a
       polymeric molecule which retains biological function. Most significant
       is the contribution of domains flanking the binding site that apparently
       enable correct folding of the latter.
