Neurobiology Draxin and Axon Guidance

Pamela J. Hines

Science, AAAS, Washington, DC 20005, USA

The developing nervous system is assembled with the help of a variety of signals and morphogens that guide the trajectory of growing neurons. Islam et al. have identified an axon guidance protein that they call draxin. Experiments in chick and mouse indicate that draxin, which appears to inhibit neurite outgrowth, is required for neurons to successfully cross the midline and form the major commissures of the brain.
