Description

NRP1 (neuropilin-1), one of the 2 members of the neuropilin family, is a single-pass type I transmembrane glycoprotein.  Both members of  neuropilins contain a large N-terminal extracellular region consisting of 2 complement-binding (CUB),  2 coagulation factor V/VIII (F5/8 type C), and 1 meprin (MAM) domains in addition to a transmembrane domain and a small cytoplasmic tail. These specific domains allow neuropilins to participate in several different types of signaling pathways that control cell survival, migration, and attraction. Neuropilins bind many ligands and various types of co-receptors including vascular endothelial growth factor (VEGF) and semaphoring (SEMA) family members.  The tandem CUB domains mediate the binding to SEMA, while the tandem F5/8 type C domains are responsible for heparin and VEGF binding. NRP1 is a 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. NRP1 mediates the chemorepulsant activity of semaphorins. NRP1 binds to SEMA3A, the PLGF-2 isoform of PGF, the VEGF-165 isoform of VEGF and VEGF-B. Coexpression with KDR results in increased VEGF-165 binding to KDR as well as increased chemotaxis. NRP1 may regulate VEGF-induced angiogenesis.  The soluble isoform of NRP1 binds VEGF-165 and appears to inhibit its binding to cells. It may also induce apoptosis by sequestering VEGF-165 and bind various members of the SEMA family. Its expression has an adverse effect on blood vessel number and integrity.
