Function

[NRP1_HUMAN] The membrane-bound isoform 1 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. It mediates the chemorepulsant activity of semaphorins. It binds to semaphorin 3A, 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. It may regulate VEGF-induced angiogenesis. The soluble isoform 2 binds VEGF-165 and appears to inhibit its binding to cells. It may also induce apoptosis by sequestering VEGF-165. May bind as well various members of the semaphorin family. Its expression has an averse effect on blood vessel number and integrity.

Publication Abstract from PubMed

Neuropilin-1 (Npn-1) is a type I cell surface receptor involved in a broad range of developmental processes, including axon guidance, angiogenesis, and heterophilic cell adhesion. We have determined the crystal structure of the human Npn-1 b1 domain to 1.9 A. The overall structure resembles coagulation factor V and VIII (F5/8) C1 and C2 domains, exhibiting a distorted jellyroll fold. Details of the structure provide insight to b1 domain regions responsible for ligand binding and facilitate rationalization of existing biochemical binding data. A polar cleft formed by adjacent loops at one end of the molecule in conjunction with flanking electronegative surfaces may represent the binding site for the positively charged tails of semaphorins and VEGF(165). The nature of the cell adhesion binding site of the b1 domain can be visualized in context of the structure.
