Plexin D1.

Plexin-A4; Involved in the development of primary sensory neurons especially in branching of the peripheral axons. Interacts with the SLIT2 signaling specifically to promote axonal branching of Rohon-Beard neurons and the trigeminal sensory ganglion neurons.

Neuropilin-1a; Receptor involved in the development of the cardiovascular system, in angiogenesis, in the formation of certain neuronal circuits and in organogenesis outside the nervous system. It mediates the chemorepulsant activity of semaphorins. Regulates angiogenesis through a VEGF-dependent pathway.

Plexin A2.

Plexin A1a.

Plexin A3; Coreceptor for class 3 semaphorins. Necessary for signaling by class 3 semaphorins and subsequent remodeling of the cytoskeleton. Plays a role in axon guidance in the developing nervous system. Class 3 semaphorins bind to a complex composed of a neuropilin and a plexin. The plexin modulates the affinity of the complex for specific semaphorins, and its cytoplasmic domain is required for the activation of down-stream signaling events in the cytoplasm.

Neuropilin; Belongs to the neuropilin family.

Plexin b1b.

Cadherin-2; Calcium-dependent cell adhesion protein; preferentially mediates homotypic cell-cell adhesion (By similarity). Cadherins contribute to the sorting of heterogeneous cell types, and thereby play an important role during embryonic development. Required for normal neural tube morphogenesis. Required to allow mid- and hindbrain neurons to reach and maintain their appropriate positions within the neural tube by restricting neuronal motility within the embryonic mid- and hindbrain.
