Sema3A-induced growth-cone collapse is mediated by Rac1 amino acids 17-32.
Neurons project their axons along specific pathways in order to establish appropriate connections with their target cells. The rate and direction of axonal growth is determined by interactions between the highly motile growth cone and environmental cues that can act in either an attractive or a repulsive manner. Locomotion is ultimately dependent upon the reorganisation of the actin cytoskeleton and an established role for the Rho family of small GTPases in regulating this process in non-neuronal cells identifies them as candidate signalling molecules in growth cones. An inactive form of Rac1 has recently been shown to inhibit the 'growth-cone collapse' response induced by chick Sema3A, a protein that has recently been established as an important guidance cue. The molecular basis for this inhibition remains unclear.
