Human NRP2/NP2/NPN2/VEGF165R2/neuropilin2 Protein, ECD (Extracellular Domain), Recombinant

Description

NRP2 (neuropilin-2), 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. NRP2 is implicated in cardiovascular development, axon guidance, and tumorigenesis. NPR2 is a high affinity receptor for SEMA3C, SEMA3F, VEGF-165 and VEGF-145 isoforms of VEGF, and the PLGF-2 isoform of PGF.
