Slit2 binding on mutant Robo1 and Robo3 receptors from various vertebrate species.
(A-D), hSlit2-D2-AP binds to COS cells expressing rRobo1K90R, rRobo1N88P but not mRobo3P84N or hRobo3. (E, F) chicken Slit2-D2-AP binds to COS cells expressing cRobo3A.1. (G, H) xSlit2-D2-AP binds to Xenopus Robo3N85P but does not bind to Robo3L127P. (I-L) zebrafish Slit2-D2-AP binds to COS cells expressing zRobo3A.1K85R but not zRobo3A.1N83P or zRobo3A.1N83P/K85R. (M) Scatchard analysis of hSlit2-D2-AP binding affinity to wild type and mutated Robo1 and Robo3 receptors. The data shown are representative of at least 3 independent experiments.
