Oncogene FLT belongs to the src gene family and is related to oncogene ROS. Like other members of this family, it shows tyrosine protein kinase activity that is important for the control of cell proliferation and differentiation. The sequence structure of the FLT gene resembles that of the FMS gene (colony stimulating factor 1 receptor), hence the name FLT was proposed as an acronym for FMS-like tyrosine kinase. An alternately spliced form of FLT1 produces a soluble protein, termed sFLT1, which binds vascular endothelial growth factor (VEGF) with high affinity. sFLT1 and FLK1 (VEGFR2) form heterodimers. FLT1 localizes in the 13q12 region of chromosome. FLT1 has been reported mostly in normal lung, but also found in placenta, liver, kidney, heart and brain tissues. It is specifically expressed in most of the vascular endothelial cells, and also expressed in peripheral blood monocytes. Isoform sFlt1 is strongly expressed in placenta.
