Alternate Name/Synonyms: VRF, VEGFL, VEGFB, VEGF-B
Gene Symbol: VEGF-B
Accession #: P49765
Gene ID: 7423
Source: HEK 293 cells
Appearance: Lyophilized powder
Physical Form Description: Lyophilized from 0.22 μm filtered solution in PBS. Generally 5-8% Mannitol or trehalose is added as a protectant before lyophilization.
Molecular Weight: The protein is fused with 6 × His tag at the C-terminus and has a calculated MW of 20.2 kDa. The predicted N-terminus is Arg 22. DTT-reduced Protein migrates as 15-18 kDa and 33-35 kDa due to glycosylation.

Background Information: Vascular endothelial growth factor B (VEGFB) also known as VEGF-related factor (VRF), is a secreted O-glycosylated protein, which belongs to the PDGF/VEGF growth factor family. VEGFB is expressed in all tissues except liver. Highest levels found in heart, skeletal muscle and pancreas. VEGFB is growth factor for endothelial cells. VEGF-B seems to play a role only in the maintenance of newly formed blood vessels during pathological conditions. VEGF-B also plays an important role on several types of neurons. It is important for the protection of neurons in the retina and the cerebral cortex during stroke and of motoneurons during motor neuron diseases such as amyotrophic lateral sclerosis.VEGF-B167 binds heparin and neuropilin-1 whereas the binding to neuropilin-1 of VEGF-B186 is regulated by proteolysis.
