    摘要: The present invention provides for a screen for a polypeptide ligand that can bind to the Tyro-10 (DDR-2) or NEP (DDR-1) receptor and that can promote a differential function and/or influence the phenotype, such as growth and/or proliferation, of cells that bear the receptor. The present invention also provides a method of screening for a molecule capable of competing with collagen for binding to the extracellular domain of a Tyro-10 (DDR-2) or NEP (DDR-1) receptor comprising contacting a sample suspected of containing the molecule with the extracellular domain of a Tyro-10 (DDR-2) or NEP (DDR-1) receptor in the presence of collagen under conditions in which the collagen is capable of binding to the extracellular domain and detecting binding of the molecule to the Tyro-10 (DDR-2) or NEP (DDR-1) receptor extracellular domain. The invention further contemplates the utilization of collagen to support the growth, survival, or differentiation of Tyro-10 (DDR-2) or NEP (DDR-1) expressing cells.
