  • FUNCTION Small GTPase playing a general role in disease resistance signaling pathway. Acts downstream of heterotrimeric G protein alpha subunit. Regulates cell death and reactive oxygen species production, probably through NADPH oxidase. Also involved in sphingolipid elicitor (SE)-dependent defense signaling. Activates phytoalexin production and alters defense-related genes. Down-regulates metallothionein 2b, a reactive oxygen scavenger (PubMed:10485927, PubMed:11149940, PubMed:12237405, PubMed:15220467). May control lignin synthesis through regulation of both NADPH oxidase and CCR1 activities during defense responses. Stimulates lignin synthesis in suspension cell culture (PubMed:15951489).SUBUNIT May interact with MPK1/MAPK6 (PubMed:15951489). Binds to RBOHB, preferentially in the GTP-bound form (PubMed:19864426). Interacts with CCR1 in a GTP-dependent manner (PubMed:16380417).INTERACTION Associated with the membrane when activated.PTM May be palmitoylated.SIMILARITY Belongs to the small GTPase superfamily. Rho family.
