| description | Heterotrimeric G protein-mediated signalling via activated 7-transmembrane (7TM) serpentine receptors is well known in a range of organisms, but evidence for the existence of this pathway in plants has been elusive. Over the years, however, evidence that G proteins are involved in signal transduction in plants has been accumulating, leading several researchers to seek plant 7TM receptors.The first tangible evidence for a plant 7TM receptor came through an analysis of the expresssed sequence tag database, dbEST. This revealed an Arabidopsis thaliana gene (GCR1) that encodes a protein with 7 predicted TM domains, and other features characteristic of known 7TM receptors [, ]. The amino acid sequence of GCR1, however, is unusual in that it shows similarity to receptors from three different 7TM families [, ], sharing greatest levels of similarity with the Dictyostelium cAMP receptors. |
