Name :
Mouse VEGF Protein, Isoform 120, Biotinylated, Recombinant

Description :
VEGF, also known as VEGF-A (vascular endothelial growth factor A) and VPF (vascular permeability factor), is the founding member of the VEGF family, including VEGF-A, VEGF-B, VEGF-C, VEGF-D, VEGF-E, and PIGF. VEGFs are secreted polypeptides with a highly conserved receptor-binding cystine-knot structure similar to that of the platelet-derived growth factors (PDGF). VEGF plays important roles in vascular development and in diseases involving abnormal growth of blood vessels such as tumor-related angiogenesis. VEGF is a growth factor active in angiogenesis, vasculogenesis and endothelial cell growth. It induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis and increases permeabilization of blood vessels. VEGF is involved in normal and pathological angiogenesis, a process that is associated with inflammation, wound healing, embryonic development, growth and metastasis of solid tumors. Elevated levels of VEGF have been detected in patients with cancer and autoimmune diseases, such as rheumatoid arthritis, multiple sclerosis, and systemic lupus erythematosus. VEGF is known to bind to the FLT1 (VEGFR1) and KDR (VEGFR2) receptors, heparan sulfate and heparin. Targeting VEGF signaling pathway has shown therapeutic benefits in multiple cancer types. Alternately spliced VEGF isoforms of 120, 164, and 188 amino acids in length exist in mouse. Isoforms other than mVEGF120 contain basic heparin­binding regions and are thus not freely diffusible. Mouse VEGF120 shares 87% sequence identity with human VEGF121.

Gene Symbol :

NCBI Gene ID :
7422 (human), 22339 (mouse)

Uniprot Entry :
P15692 (human), Q00731 (mouse)

Construct Details :
Mouse VEGF120 is expressed as a 131-amino acid protein consisting of the region Ala27 – Arg146 of mouse VEGF (UniProt Accession #Q00731-3, isoform VEGF120) and a C-terminal His-tag. It contains 1 potential sites for N-linked glycosylation and and exists as a dimer under non-reducing condition (see the gel image inserted).
