General Information

General Information	Comment	Organism
physiological function	the enzyme interacts with the alpha subunit of the heterotrimeric G-protein complex in Arabidopsis and affects etiolation and leaf morphology. The enzyme plays a key role in the signaling pathway controlling hypocotyl length in dark grown seedlings and in leaf morphology	Arabidopsis thaliana
