Predicted to enable calmodulin binding activity and phospholipid binding activity. Acts upstream of or within axon choice point recognition; cell fate commitment; and glial cell differentiation. Located in several cellular components, including axon; plasma membrane; and postsynaptic density. Is expressed in several structures, including alimentary system; future brain; genitourinary system; nervous system; and sensory organ. Orthologous to human GAP43 (growth associated protein 43).
