Human Neuropilin-1 / NRP1 / CD304 Protein, Fc Tag

  • Synonym
    NRP1,Neuropilin-1,NRP,VEGF165R,CD304
  • Source
    Human NRP1, Fc Tag (NR1-H5252) is expressed from human 293 cells (HEK293). It contains AA Phe 22 - Lys 644 (Accession # AAH07533).
    Predicted N-terminus: Phe 22
  • Molecular Characterization
    Online(Phe 22 - Lys 644) AAH07533

    This protein carries a human IgG1 Fc tag at the C-terminus.

    The protein has a calculated MW of 96.5 kDa. The protein migrates as 105-130 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

  • Background
    Neuropilin-1 (NRP1) is also known as Vascular endothelial cell growth factor 165 receptor (VEGF165R), CD antigen CD304, which belongs to the neuropilin family. 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.
