This protein is associated with nerve growth. It is a major component of the motile 'growth cones' that form the tips of elongating axons. Plays a role in axonal and dendritic filopodia induction (By similarity). Binds calmodulin with a greater affinity in the absence of Ca(2+) than in its presence. Palmitoylated (By similarity). Palmitoylation is essential for plasma membrane association (By similarity). Belongs to the neuromodulin family.
