Flt1, Human, Control Peptide (Fms-like Tyrosine Kinase 1, Vascular Endothelial Growth Factor Receptor 1, VEGF R1)

Embryonic vascular system undergoes a series of complex, highly regulated series of events involving differentiation, migration and association of primitive endothelial cells. This process is termed vasculogenesis. A further remodeling of the primitive vascular system forms the mature cardiovascular system. This process is known as angiogenesis (sprouting of new capillary vessels from pre-existing vasculature). Study of tumor angiogenesis has led to the identification of several proteins including basic fibroblast growth factor (bFGF) and vascular endothelial growth factor. VEGF acts by interacting with a family of largely endothelial-specific receptor tyrosine kinases that includes VEGFR-1 (flt-1/flk-2), VEGFR-2 (flk-1/KDR), and VEGFR-3/Flt-4. Disruption of VEGFRs interferes with differentiation of endothelial cells and it is lethal for the embryo.
FLT-1 (fms-like tyrosine kinase or VEGF-R1; human 1338 aa; rat 1336 aa, and mouse 1330aa), a putative receptor protein tyrosine kinase, is a receptor for VEGF and PLGF. It is type 1 membrane protein. It is expressed in normal lung, placenta, liver, kidney, heart, and brain but not in tumor.
