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.,BDCA4,CD304,NP1,NRP,VEGF165R,Neuropilin-1,NRP1,Cell Biology & Developmental Biology,Growth factor,VEGF,VEGF Receptors,Immunology & Inflammation,CD markers,Neuroscience,Stem Cells,Cardiovascular,Angiogenesis,NRP1
