Neuropilin-1 is a type 1 membrane protein expressed in developing neurons. Neuropilin-1 binds class 3 semaphorins including Sema3A which can induce neuronal growth cone collapse and repulsion of axons. To clarify the roles of neuropilin-l-mediated Sema3A signals in vivo, we produced neuropilin-l-deficient and Sema3A-deficient mutant mice by targeted disruption of the neuropilin-1-and Sema 3A genes, respectively. Neuropilin-l-deprived dorsal root ganglion neurons were perfectly protected from growth cone collapse elicited by Sema3A.
