Background: Neuropilin-1

Neuropilin-1 (also known as Npn-1, NRP1, neuropilin, or CD304/BDCA4) is a 923 amino acid (aa) type I transmembrane glycoprotein (theoretical molecular weight 130-140 kDa) located on human chromosome 10p11.22 that encodes multiple intact and soluble isoforms. The 623 aa extracellular domain (ECD) of this human cell surface receptor includes two CUB (complement-binding) domains, two F5/8 domains with homology to coagulation factors V and VIII, and a MAM (meprin) domain. The ECD of human Neuropilin-1 shares 92-95% aa sequence identity with mouse, rat, bovine, and canine Npn-1. The MAM domains of neuropilins are involved in the formation of homo- and hetero-oligomers in the absence of ligands. Neuropilin-1 expression is found in neuronal, endothelial and tumor cells as well as epithelial cells such as in the respiratory, gastrointestinal, lower urological tracts, thyroid, parathyroid and thymus gland (1,2).
Initially found to play an essential role in axon growth and guidance, NRP1 serves as a multifunctional co-receptor for class III semaphorins and heparin-binding members of the VEGF family, participating in regulation of angiogenesis, neuronal development, cell survival, migration and tumor-invasion. Neuropilin-1 has been implicated in viral infections and T-cell activation and is also described as a marker of regulatory T (Treg) cells (3). In COVID-19 infections, studies have shown NRP1 participates in viral infection via NRP1 neutralizing antibodies and binds the SARS-CoV-2 Spike protein, suggesting NRP1 may contribute to viral transport and viral internalization by endocytosis (4).
