Western blot - Recombinant mouse VEGFA protein (Active) (AB185265)

This blot was produced using a 10% Bis-tris gel under the MES buffer system. The gel was run at 200V for 35 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 3% Milk before being incubated with ab46154 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution.

Supplementary information

Vascular endothelial growth factor A (VEGFA) also known as VEGF or vascular permeability factor (VPF) is a protein that plays a central role in angiogenesis as well as in the growth of blood vessels. The molecular weight of VEGFA varies depending on the isoform typically ranging from 34 to 42 kDa. VEGFA is expressed in many tissues including fibroblasts macrophages endothelial cells and platelets. Its expression levels can increase in response to stimuli like hypoxia or inflammatory cytokines. VEGFA is an important target in research for therapies related to vascular diseases and cancer.
Biological function summary

VEGFA functions by promoting the proliferation and migration of vascular endothelial cells. It operates both as a homodimer and as part of complex signaling cascades interacting with VEGF receptors on cell surfaces to trigger downstream signals for angiogenesis. This includes endothelial cell growth migration and the new blood vessel formation process. VEGFA's activity is important for physiological processes such as wound healing and embryonic development and it also contributes to pathological conditions through its unregulated expression in diseases.

Pathways

Many processes involve VEGFA including the PI3K/AKT pathway and the MAPK/ERK pathway. These pathways regulate cell survival growth and differentiation. Other proteins like PLGF (placenta growth factor) and VEGFB often accompany VEGFA in these pathways aiding in distinct but overlapping roles. These interactions are transmitted through binding to VEGF receptors such as VEGFR-1 and VEGFR-2 subsequently activating various signaling cascades necessary for cellular and tissue homeostasis.

VEGFA relates to cancer and age-related macular degeneration among others. In cancer overexpression of VEGFA can lead to excessive angiogenesis supplying blood to tumors and facilitating tumor growth. In age-related macular degeneration upregulation of VEGFA contributes to the progression of the disease by promoting the formation of abnormal blood vessels under the retina. Anti-VEGFA therapies such as anti-VEGF antibodies (e.g. bevacizumab) can target these overexpressed pathways. VEGFA interacts with other proteins like HIF-1α which regulates its expression under hypoxia a common condition in tumors.

General info

Function

N-VEGF. Participates in the induction of key genes involved in the response to hypoxia and in the induction of angiogenesis such as HIF1A (PubMed : 35455969). Involved in protecting cells from hypoxia-mediated cell death (PubMed : 35455969).. VEGFA. Growth factor active in angiogenesis, vasculogenesis and endothelial cell growth. Induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis and induces permeabilization of blood vessels. Binds to the FLT1/VEGFR1 and KDR/VEGFR2 receptors, heparan sulfate and heparin. Binds to the NRP1/neuropilin-1 receptor. Binding to NRP1 receptor 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 (PubMed : 26503042). Also binds the DEAR/FBXW7-AS1 receptor (PubMed : 16293765). May play a role in increasing vascular permeability during lactation, when increased transport of molecules from the blood is required for efficient milk protein synthesis (By similarity).

Sequence similarities

Belongs to the PDGF/VEGF growth factor family.

Post-translational modifications

Vascular endothelial growth factor A, long form. Produced by use of an alternative upstream CUG codon and post-translationally processed into the N-terminal N-VEGF form and the C-terminal secreted VEGFA form.
