Raftlin is recruited by neuropilin-1 to the activated VEGFR2 complex to control proangiogenic signaling.

Nrp1 is an important co-receptor for VEGFR2; however, its functions are still only partially understood. We show that raftlin works with Nrp1 in endothelial cells to control intracellular trafficking of the activated VEGFR2. This modulates the response to VEGF and controls endothelial cell migration.
