Neuropilin
(重定向自Neuropilins)

Neuropilin is a protein receptor active in neurons.
There are two forms of Neuropilins, NRP-1 and NRP-2. They are transmembrane glycoproteins, and predominantly co-receptors for another class of proteins known as semaphorins. Of the semaphorins, NRP-1 and NRP-2 are specifically receptors for class-3 semaphorins, which, among many things, are responsible for axon guidance during the development of the nervous system in vertebrates.
