Profilins belong to a family of small G-actin binding proteins which are thought to assist in F-actin elongation at the leading edge of migrating cells through their interactions with a host of actin-binding proteins including Ena (enabled)/VASP (vasodilator stimulated phosphoprotein). Profilin's interactions with the major actin regulators have been studied almost exclusively using biochemical methods. Therefore spatiotemporal features of these protein–protein interactions have not been resolved so far. In this paper, we for the first time demonstrate the feasibility of GFP-based fluorescence resonance energy transfer (FRET) technique to detect VASP's interaction with profilin-1, a ubiquitously expressed member of profilin family of genes. Specifically, we performed acceptor photobleaching FRET in MDA-MB-231 breast cancer cells to show prominent VASP–Pfn1 interaction at the membrane ruffles near the leading edge.
