Abstract excerpt

Rho of Plants (ROPs) are plant-specific Rho GTPases that regulate diverse cellular processes. Based on their C-terminal motifs, ROPs are classified as type I or type II. Type-II ROPs lack the canonical CaaL prenylation motif and can be palmitoylated in vitro, yet in vivo evidence for their S-acylation and functional significance has been limited. Here, we investigated the membrane association, lipid modifications...
