  • Function

    Receptor for VEGF, VEGFB and PGF. Has a tyrosine-protein kinase activity. The VEGF-kinase ligand/receptor signaling system plays a key role in vascular development and regulation of vascular permeability. Isoform SFlt1 may have an inhibitory role in angiogenesis.
  • Tissue specificity

    Mostly in normal lung, but also in placenta, liver, kidney, heart and brain tissues. Specifically expressed in most of the vascular endothelial cells, and also expressed in peripheral blood monocytes. Isoform sFlt1 is strongly expressed in placenta.
  • Sequence similarities

    Belongs to the protein kinase superfamily. Tyr protein kinase family. CSF-1/PDGF receptor subfamily.
    Contains 7 Ig-like C2-type (immunoglobulin-like) domains.
    Contains 1 protein kinase domain.
  • Cellular localization

    Secreted and Cell membrane.
  • Information by UniProt


  • Inhibition of the VEGF165-induced proliferation of HUVE cells by recombinant human endogenous sFlt-1 and sFlt-1 constructs. HUVECs were stimulated with 10 ng/ml VEGF165, the soluble receptors were added with a 100X excess.
  • SDS-PAGE analysis of recombinant human soluble VEGFR-1D1-4 produced in insect cells. Sample was loaded in 10% SDS-polyacrylamide gel under reducing condition and stained with Silver stain.
