Rho-dependent and -independent activation mechanisms of ERM proteins: an essential role for polyphosphoinositides in vivo.
ERM proteins crosslink actin filaments to plasma membranes and are involved in the organization of the cortical cytoskeleton, especially in the formation of microvilli.
ERM proteins are reported to be activated as crosslinkers in a Rho-dependent manner and are stabilized when phosphorylated at their C-terminal threonine residue to create C-terminal threonine- phosphorylated ERM proteins
However, ERM proteins appear to be activated in the absence of Rho activation and remain active without C-terminal phosphorylation.
Phosphatidylinositol (4,5)-bisphosphate (PtdIns(4,5)P2) affected the activation of ERM proteins regardless of cell type.
The Rho-independent activation mechanism of ERM proteins therefore exists.
Both Rho-dependent and -independent activation of ERM proteins require a local elevation of PtdIns(4,5)P2 concentration in vivo.
