BINDING OF OSTEOGENIC PROTEIN-I (OP-1) AND ANALOGS THEREOF TO THE CELL SURFACE RECEPTOR ALK-1 AND ANALOGS THEREOF

摘要

Disclosed are (1) nucleic acid sequences, amino acid sequences, homologies, structural features, and various other data characterizing morphogen cell surface receptors, particularly OP-1-binding cell surface receptors, e.g., ALK-1; (2) methods for producing receptor proteins, including fragments thereof, using recombinant DNA technology; (3) methods for identifying novel morphogen receptors and their encoding DNAs; (4) methods for identifying compounds capable of modulating endogenous morphogen receptor levels; and (5) methods and compositions for identifying and producing morphogen analogs useful in the design of morphogen agonists and antagonists for therapeutic, diagnostic, and experimental uses.
