Regulating the motor for GLUT4 vesicle traffic.
Insulin-triggered trafficking of GLUT4 glucose transporter-loaded vesicles and their fusion with the plasma membrane are mechanical processes involving multiprotein complexes that coordinate and facilitate vesicle movement. Now, Yip et al. (2008) link myosin-1c to insulin signaling by demonstrating direct CaMKII-driven phosphorylation of this critical motor protein.
