Growth factor for endothelial cells. VEGF-B167 binds heparin and neuropilin-1 whereas the binding to neuropilin-1 of VEGF-B186 is regulated by proteolysis. Homodimer; disulfide-linked. Can also form heterodimer with VEGF. Expressed in all tissues except liver. Highest levels found in heart, skeletal muscle and pancreas. Belongs to the PDGF/VEGF growth factor family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
