Figure 1From: Protein evolution of Toll-like receptors 4, 5 and 7 within Galloanserae birdsDifferences in ECD surface electrostatic potentials between birds and mammals (for a full comparison see Additional file2: Figure S5). (a) TLR4, (b) TLR5, (c) TLR7; positive surface charge is highlighted in red, negative charge in blue; the predicted functional sites in ECD are outlined in yellow in the GaGaTLR models; GaGa = chicken Gallus gallus, AnAn = goose Anser anser, AnPl = duck Anas platyrhynchos, HoSa = human Homo sapiens, MuMu = mouse Mus musculus.Back to article page
