Abstract: Robo1 and Robo2 polypeptides may be produced recombinantly from transformed host cells from the disclosed Robo encoding nucleic acids or purified from human cells. The invention provides isolated Robo hybridization probes and primers capable of specifically hybridizing with the disclosed Robo genes, Robo-specific binding agents such as specific antibodies, and methods of making and using the subject compositions in diagnosis, therapy and in the biopharmaceutical industry.

Abstract: 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.

Abstract: A novel class of proteins, semaphorins, nucleic acids encoding semaphorins, semaphorin peptides, and methods of using semaphorins and semaphorin-encoding nucleic acids are disclosed. Semaphorin peptides and receptor agonists and antagonists provide potent modulators of nerve cell growth and regeneration. The invention provides pharmaceutical compositions, methods for screening chemical libraries for regulators of cell growth/differentiation; semaphorin gene-derived nucleic acids for use in genetic mapping, as probes for related genes, and as diagnostic reagents for genetic neurological disease; specific cellular and animal systems for the development of neurological disease therapy.

Abstract: The amount of active Robo expressed on a cell is modified by modulating the effective amount of a Comm polypeptide in contact with the cell, whereby the amount of expressed active Robo is modulated inversely with the modulation of the effective amount of the Comm polypeptide in contact with the cell. In a particular embodiment, the Comm polypeptide is provided to the cell by exogenously in a pharmaceutically acceptable composition. In another aspect, the invention provides methods of screening for agents which modulate Robo-Comm interactions. These methods generally involve forming a mixture of a Robo-expressing cell, a Comm polypeptide and a candidate agent, and determining the effect of the agent on the amount of Robo expressed by the cell.
