Semaphorin-3C is a protein that in humans is encoded by the SEMA3C gene. [5] [6] [7]
Neuropilin is a protein receptor active in neurons.
A plexin is a protein which acts as a receptor for semaphorin family signaling proteins. It is classically known for its expression on the surface of axon growth cones and involvement in signal transduction to steer axon growth away from the source of semaphorin. Plexin also has implications in development of other body systems by activating GTPase enzymes to induce a number of intracellular biochemical changes leading to a variety of downstream effects.
Neuropilin 2 (NRP2) is a protein that in humans is encoded by the NRP2 gene.
Neuropilin-1 is a protein that in humans is encoded by the NRP1 gene. In humans, the neuropilin 1 gene is located at 10p11.22. This is one of two human neuropilins.
Semaphorin-3A is a protein that in humans is encoded by the SEMA3A gene.
Semaphorin-4D (SEMA4D) also known as Cluster of Differentiation 100 (CD100), is a protein of the semaphorin family that in humans is encoded by the SEMA4D gene.
Semaphorin-3F is a protein that in humans is encoded by the SEMA3F gene.
Semaphorin-3B is a protein that in humans is encoded by the SEMA3B gene.
Plexin-A1 is a protein that in humans is encoded by the PLXNA1 gene.
Semaphorin-4F is a protein that in humans is encoded by the SEMA4F gene.
Semaphorin 7A, GPI membrane anchor (SEMA7A) also known as CD108, is a human gene.
Semaphorin-5A is a protein that in humans is encoded by the SEMA5A gene.
Semaphorin-4A is a protein that in humans is encoded by the SEMA4A gene.
Semaphorin-4B is a protein that in humans is encoded by the SEMA4B gene.
Semaphorin-4C is a protein that in humans is encoded by the SEMA4C gene.
Plexin-A4 is a protein that in humans is encoded by the PLXNA4 gene.
Semaphorin-6A is a protein that in humans is encoded by the SEMA6A gene.
The growth cone is a highly dynamic structure of the developing neuron, changing directionality in response to different secreted and contact-dependent guidance cues; it navigates through the developing nervous system in search of its target. The migration of the growth cone is mediated through the interaction of numerous trophic and tropic factors; netrins, slits, ephrins and semaphorins are four well-studied tropic cues (Fig.1). The growth cone is capable of modifying its sensitivity to these guidance molecules as it migrates to its target; this sensitivity regulation is an important theme seen throughout development.
Semaphorin 3E is a protein that in humans is encoded by the SEMA3E gene.
