High impact information on RIC4

Locally activated ROP2, a Rho-related GTPase from plants, activates RIC4 to promote the assembly of cortical actin microfilaments required for localized outgrowth [1].
RIC4 promotes F-actin assembly, whereas RIC3 activates Ca(2+) signaling that leads to F-actin disassembly [2].
