產(chǎn)品描述：

The gene fragment coding for amino acids 22-644 of the human Neuropilin-1 (NRP1) isoform 2 is expressed in mammalian cells with a human Fc tag at the C-terminus. The product is the recombinant human NRP1 protein. This NRP1 protein has been demonstrated to be active. In the functional ELISA, immobilized human VEGF165 can bind to this NRP1 protein. The EC₅₀ is 22.68-34.55 ng/ml. It reaches up to 95% in purity. In the SDS-PAGE, this protein migrated to the band of molecular weight about 116 kDa on the gel. Its endotoxin is less than 1.0 EU/ug determined by the LAL method. This recombinant NRP1 protein is in stock.

NRP1, a member of a family of signaling and catalytic proteins, exists as two isoforms: a secreted form (sNRP1) and a transmembrane form. sNRP1 has been known to suppress cell-associated NRP-1 function in cervical cancer. And patients with cervical cancer have significantly higher circulating sNRP-1 levels. The transmembrane form of NRP1 plays important roles in the development of the nervous and cardiovascular system, tumorgenesis, and viral entry through interaction with VEGF, Sema3A, TGF-β, plexins, and integrins. Studies have demonstrated that NRP1 facilitates SARS-CoV-2 entry into host cells and significantly potentiates SARS-CoV-2 infectivity in vitro. NRP1 thus may potentially provide a therapeutic target for COVID-19.

靶點(diǎn)詳情

功能：

Cell-surface 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. Mediates the chemorepulsant activity of semaphorins. Recognizes a C-end rule (CendR) motif R/KXXR/K on its ligands which causes cellular internalization and vascular leakage. It binds to semaphorin 3A, the PLGF-2 isoform of PGF, the VEGF165 isoform of VEGFA and VEGFB. Coexpression with KDR results in increased VEGF165 binding to KDR as well as increased chemotaxis. Regulates VEGF-induced angiogenesis. Binding to VEGFA initiates a signaling pathway needed for motor neuron axon guidance and cell body migration, including for the caudal migration of facial motor neurons from rhombomere 4 to rhombomere 6 during embryonic development. Regulates mitochondrial iron transport via interaction with ABCB8/MITOSUR.; Binds VEGF-165 and may inhibit its binding to cells. May 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.; (Microbial infection) Acts as a host factor for human coronavirus SARS-CoV-2 infection. Recognizes and binds to CendR motif RRAR on SARS-CoV-2 spike protein S1 which enhances SARS-CoV-2 infection.
