Robo is Abl to block N-Cadherin function

The molecular pathways involved in wiring the brain have just begun to be elucidated. Work in this issue of Nature Cell Biology has uncovered inhibitory interactions between two such pathways: Roundabout (Robo) and N-Cadherin. This discovery provides a potential mechanistic understanding of how pathways are used in a coordinated manner to guide axons.
