Plant phosphosites are enriched at well-conserved phospho-acceptor positions across 7TM-RGS proteins. (A) Residue conservation (% identity) derived from multiple sequence alignment (MSA) of 7TM-RGS proteins from plants. Black bars indicate the position of the 7TM and RGS domains. (B) Alignment position locations of plant phosphosites observed in the cytoplasmic C-terminal end of 7TM-RGS proteins. Only alignment positions 400–1000 are shown. Size of each circle indicates the percent conservation of phospho-acceptor residues (S,T,Y) within the alignment position of each observed phosphosite. (C) Table of the average residue conservation (% identity) and phospho-acceptor residue conservation (% S,T,Y) in the 14 phosphosite alignment positions (top) versus all other alignment positions that harbor at least one phospho-acceptor residue in the cytoplasmic region of 7TM-RGS.
