摘要:
The invention provides methods and compositions relating to vertebrate UNC-5 proteins which function as receptor proteins for netrins, a family of cell guidance proteins. The proteins may be produced recombinantly from transformed host cells from the disclosed vertebrate UNC-5 encoding nucleic acid or purified from human cells. The invention provides specific hybridization probes and primers capable of specifically hybridizing with the disclosed vertebrate unc-5 gene, vertebrate UNC-5-specific binding agents such as specific antibodies, and methods of making and using the subject compositions in diagnosis, therapy and in the biopharmaceutical industry.

摘要:
Disclosed are methods and compositions for identifying agents which modulate the interaction of Robo and a Robo ligand and for modulating the interaction of Robo and a Robo ligand. The methods for identifying Robo:ligand modulators find particular application in commercial drug screens. These methods generally comprise (1) combining a Robo polypeptide, a Slit polypeptide and a candidate agent under conditions whereby, but for the presence of the agent, the Robo and Slit polypeptides engage in a first interaction, and (2) determining a second interaction of the Robo and Slit polypeptides in the presence of the agent, wherein a difference between the first and second interactions indicates that the aget modulates the interaction of the Robo and Slit polypeptides. The subject methods of modulating the interaction of Robo and a Robo ligand involve combining a Robo polypeptide, a Slit polypeptide and a modulator under conditions whereby, but for the presence of the modulator, the Robo and Slit polypeptides engage in a first interaction, whereby the Robo and Slit polypeptides engage in a second interaction different from the first interaction. In a particular embodiment, the modulator is dominant negative form of the Robo or Slit polypeptide.

Compositions for identifying lead compounds for pharmacological agents useful in the diagnosis or treatment of neurological disease or injury include mixtures comprising an isolated netrin and an isolated natural netrin receptor such as "Deleted in Colorectal Carcinoma" (DCC) and neogenin. The general methods involve incubating a mixture of an isolated mammalian netrin, an isolated natural mammalian netrin receptor, and a candidate pharmacological agent, and determining if the presence of the agent modulates the binding of the netrin to the receptor.

摘要:
A novel classes of neural axon outgrowth promoting and orienting proteins, nucleic acids encoding such proteins and receptors which selectively bind such proteins are disclosed. The disclosed neural axon outgrowth promoting and orienting proteins include the laminin-related p75/p78 family; a family of vertebrate proteins which promote axon outgrowth and/or orientation, and p75/p78 family-specific receptors, including receptors found on spinal nerve axons, especially growth cones. Also disclosed are agents including peptides derived from the disclosed neural axon outgrowth promoting proteins capable of effecting axon outgrowth, orientation and regeneration. These agents provide small molecular weight modulators of nerve cell growth useful in the treatment of neurological disease and injury. The disclosed compositions also find use variously in screening chemical libraries for regulators of axon outgrowth and orientation, in genetic mapping, as probes for related genes, as diagnostic reagents for genetic neurological disease and in the production of specific cellular and animal systems for the development of neurological disease therapy.
