We identify and characterize two novel Arabidopsis proteins that show homology to an orphan vertebrate GPCR (GPR89) and interact with the sole Arabidopsis G protein alpha subunit, GPA1, but also have intrinsic GTP-binding and GTPase activity.

20353092 Hao L, Yu C, Li B, Wang D: [Molecular cloning and preliminary analysis of TaNOA in common wheat] . Sheng Wu Gong Cheng Xue Bao. 2010 Jan;26(1):48-56.

TaNOA transcript level was up-regulated by abscisic acid (ABA) or NaC1 treatments, indicating that TaNOA might be involved in wheat responses to abiotic stresses.
The primary structure of TaNOA-B1 contained the zinc finger and P-loop GTPase motifs conserved in Arabidopsis and rice NOA1 proteins.

A small GTPase, Rac1, plays a key role in rice (Oryza sativa) innate immunity as part of a complex of regulatory proteins.
RACK1A transcription was also induced by a fungal elicitor and by abscisic acid, jasmonate, and auxin.

Promoter analysis showed that OsRacB promoter is induced by salinity and exogenous salicylic acid, not abscisic acid.

The regulator of G-protein signaling (RGS) proteins, recently identified in Arabidopsis (Arabidopsis thaliana; named as AtRGS1), has a predicted seven-transmembrane structure as well as an RGS box with GTPase-accelerating activity and thus desensitizes the G-protein-mediated signaling.

Prenylation is a posttranslational protein modification essential for developmental processes and response to abscisic acid.
Here we show that in yeast (Saccharomyces cerevisiae) AtRCE1 promoted a-mating factor secretion and membrane localization of a ROP GTPase.
