Figure 3From: Common peptides shed light on evolution of Olfactory ReceptorsCP coverage of positions along the OR sequence. Positions start from the N-terminal (N), through Transmembrane domains 1–7 (T1–T7), Intracellular loops (I1–I3) and extracellular loops (E1–E3) and end in the C-terminal (C). 65 known highly-conserved positions are indicated by red.Back to article page
