Function

function

May be involved in cell polarity control during the actin-dependent tip growth of pollen tubes.
Inactive GDP-bound Rho GTPases reside in the cytosol, are found in a complex with Rho GDP-dissociation inhibitors (Rho GDIs), and are released from the GDI protein in order to translocate to membranes upon activation.
