NEUROBIOLOGY Knowing When to Branch

Neuronal axons form branches to establish precise connections with their targets, but branch control is not well understood. Colavita and Tessier-Lavigne have identified a subset of neurons in Caenorhabditis elegans that require a membrane protein called BAM-2 (branching abnormal) to stop formation of branches and to stabilize their termination. Loss of BAM-2 allowed branches to overshoot their normal termination sites. BAM-2 shows sequence similarity to neurexins that are thought to control the stability of neuronal synapses.
