FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes one of two neuropilins, which contain specific protein domains which allow them to participate in several different types of signaling pathways that control cell migration. Neuropilins contain a large N-terminal extracellular domain, made up of complement-binding, coagulation factor V/VIII, and meprin domains. These proteins also contains a short membrane-spanning domain and a small cytoplasmic domain. Neuropilins bind many ligands and various types of co-receptors; they affect cell survival, migration, and attraction. Some of the ligands and co-receptors bound by neuropilins are vascular endothelial growth factor (VEGF) and semaphorin family members. Several alternatively spliced transcript variants that encode different protein isoforms have been described for this gene. [provided by RefSeq, Oct 2011]
PHENOTYPE: Homozygous null mice show embryonic death, impaired neuronal migration and axon guidance, and vascular defects including a disorganized yolk sac vascular plexus, and malformed brachial arch arteries and great vessels. Mice lacking the cytoplasmic domain show altered retinal arteriovenous patterning. [provided by MGI curators]
