NCBI Protein Information
RHO-related protein from plants 2
NCBI Summary
Member of the Rho GTPase family. Functions to organize the microtubular cytoskeleton in combination with RIC1 and RIC4. These interactions affect pavement cell morphogenesis and pollen tube growth. ROP2 expression is stimulated by brassinosteroid treatment. Inhibit light-induced stomatal opening.

UniProt Comments
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 . May be involved in cell polarity control during the actin-dependent tip growth of root hairs. May regulate a WAVE complex that activates the Arp2/3 complex.
