VASP and cancer: Previously, we found that Lpd is phosphorylated by Abl kinases upon growth factor stimulation, and this positively regulates its interaction with Ena/VASP proteins and their recruitment to the leading edge of cells.19 As Src kinases are also activated upon growth factor stimulation and increased Src activity promotes cancer cell invasion,40 we explored whether Lpd interactions with downstream partners are regulated by Src phosphorylation.
