    • 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.
    • 公开了用于鉴定调节Robo和Robo配体的相互作用并调节Robo和Robo配体的相互作用的试剂的方法和组合物。 用于鉴定Robo:配体调节剂的方法在商业药物筛选中发现具体应用。 这些方法通常包括(1)在条件下组合Robo多肽,狭缝多肽和候选试剂,但是对于所述试剂的存在,所述Robo和狭缝多肽参与第一相互作用,和(2)确定第二相互作用 的Robo和Slit多肽,其中所述第一和第二相互作用之间的差异指示所述琼脂调节所述Robo和Slit多肽的相互作用。 调节Robo和Robo配体的相互作用的主题方法包括在条件下组合Robo多肽,狭缝多肽和调节剂,但是对于调节剂的存在,Robo和Slit多肽参与第一相互作用,由此 Robo和Slit多肽参与与第一相互作用不同的第二相互作用。 在一个具体实施方案中,调节剂是Robo或Slit多肽的显性阴性形式。
