Figure 5

Amino-acid Bayesian tree showing basal metazoan repertoire of type II/I receptors. Trichoplax adhaerens (prefix Ta – in blue), Nematostella vectensis (in green) and fly proteins (Babo, Tkv, Sax, Put, wit) are shown. N. vectensis sequences were retrieved from GenBank: type I receptors – EDO30434, EDO41833, EDO49083; type II receptors – EDO41379, and EDO49370 (with splice variant AAS77521). The tree is rooted using EDO41379. Branch lengths are shown in red. Node probabilities are shown in black.
