Rho1 signaling is activated by G-protein-coupled receptor (GPCR) signaling at the cell surface. During Drosophila embryonic salivary gland (SG) invagination, the GPCR ligand Folded gastrulation (Fog) activates The SG receptor that transduces the Fog signal into Rho1-dependent myosin activation has not been identified , we reveal that the Smog GPCR transduces Fog signal to regulate Rho kinase accumulation and myosin activation
