"L1 interacts with neuropilin 1 (NP-1) through a conserved sequence (FASNKL) present with in the Ig1 domain of L1 and this association is required as a part of semaphorin 3A (Sema3A) receptor complex for axon guidance responses.
L1 interacts with NP-1 in cis to form a receptor complex that induces repulsive turning of the growth cone in response to Sema3A binding, whereas trans interaction of L1 with NP-1 switches Sema3A triggered repulsion to attraction."^^ . . . . . . "L1 binds Neuropilin-1"^^ . . . .
