Abstract

See full text

Chimeric heteromultimer adhesins that bind the ligand of natural heromultimeric receptors and uses therefor are disclosed. The chimeric molecules of the heteromultimer adhesins comprise an extracellular domain of a heteromultimeric receptor monomer and a multimerization domain for the stable interaction of the chimeric molecules in the adhesin. Specifically disclosed are heteromultimeric adhesins comprising the extracellular domains of the ErbB2 and ErbB3 and ErbB2 and ErbB4. The chimeric ErB heteromultimer adhesins of the present invention are useful as competitive antagonists or agonists of a neuregulin for the treatment of diseases such as various cancers.
