ROK translocates to the plasma membrane fraction; however, the mechanism of the translocation of ROK still remains obscure. To clarify the molecular mechanisms of the translocation of ROK, we co-transfected MDCK cells with cyan fluorescent protein-tagged RhoA and yellow fluorescent protein-tagged ROKalpha, or their variants, and monitored the localization and translocation of the two different fluorescent tagged-molecules in single living cells during epithelial growth factor (EGF) stimulation. Both RhoA (wild-type) and ROKalpha (wild-type) translocated to ruffling membrane with EGF stimulation in several minutes. A ROKalpha mutant, in which Rho-binding ability is disrupted, is unable to translocate to the membrane with RhoA. However, RhoA mutant Q63L/C190R, an active form lacking membrane localization activity, abolished the translocation of wild-type ROKalpha, suggesting that the translocation of RhoA is critical for ROK translocation to the membrane. Another mutant lacking the pleckstrin homology domain failed in translocation as well. On the other hand, it was surprising that the kinase dead mutant succeeded in translocation to the membrane after EGF stimulation. Based on these results, we propose the following ROKalpha translocation mechanism. ROKalpha binds to RhoA in cytosol and translocates to the membrane based on the membrane-targeting ability of active RhoA. After ROKalpha associates with the membrane, the pleckstrin homology domain provides the stability of ROKalpha on the membrane. The activation of enzymatic activity or adenosine triphosphate binding, however, is not directly related to the translocation mechanism, although we found that the membrane association is critical for the activation of the kinase activity."xsd:string |
