CC -!- FUNCTION: Acts as a negative regulator of abscisic acid (ABA)
CC responses. {ECO:0000269|PubMed:12417701}.
CC -!- SUBUNIT: Interacts with ICR1 (PubMed:17493810). Binds to SPK1
CC (PubMed:18308939). {ECO:0000269|PubMed:17493810,
CC ECO:0000269|PubMed:18308939}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000269|PubMed:12368496}; Lipid-
CC anchor {ECO:0000269|PubMed:12368496}.
CC -!- PTM: Although this sequence has a C-terminal -CXXX, it is palmitoylated
CC at Cys-205, rather than prenylated. {ECO:0000269|PubMed:12368496}.
CC -!- SIMILARITY: Belongs to the small GTPase superfamily. Rho family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAB41135.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
