Receptors for VEGF isoforms. Flt-1 is VEGF Receptor-1; flt-3 (Flk2; STK-1; CD135) has a ligand of 24 kD similar to c-kit ligand and M-CSF; flt-4 (VEGFR-3) binds VEGF-C and is mainly restricted to lymphatic endothelium during development. All are receptor tyrosine kinases and are involved in regulation of endothelial or haematopoietic cell development.
