Roundabouts (robo) are cell-surface receptors that mediate repulsive signaling mechanisms at the central nervous system midline. However, robos may also mediate attraction mechanisms in the context of vascular development. Here, we have performed structure-function analysis of roundabout4 (Robo4), the predominant robo expressed in embryonic zebrafish vasculature and found by gain of function approaches in vitro that Robo4 activates Cdc42 and Rac1 Rho GTPases in endothelial cells. Indeed… CONTINUE READING
