Plexin-A1 (PLXNA1)

Coreceptor for SEMA3A, SEMA3C, SEMA3F and SEMA6D.

Necessary for signaling by class 3 semaphorins and subsequent remodeling of the cytoskeleton.

Plays a role in axon guidance, invasive growth and cell migration. Class 3 semaphorins bind to a complex composed of a neuropilin and a plexin.
