A non-membrane associated splice variant of VEGF receptor 1 (Flt-1), sFlt-1 binds the angiogenic factors VEGF (vascular endothelial growth factor) and PlGF (placental growth factor), reducing blood vessel growth through reduction of free VEGF and PlGF concentrations. (wikipedia.org)
As it contains the same extracellular domain as Flt-1, sFlt-1 competes with Flt-1 to bind VEGF and PIGF, effectively reducing serum concentrations of these two angiogenic growth factors. (wikipedia.org)
