In this study, the authors show that Celsr3 and Fzd3 interact in motor neurons to cooperatively direct axon guidance to target muscles in the periphery. In addition, they find that loss of Celsr3 or Fzd3 function also impairs axonal responses to ephrinA reverse, attractive signaling, suggesting a functional interaction between these guidance pathways.
