Motif analysis for Latimeria T2R and V1R/ORA receptors confirms results of the phylogenetic analysis. Sequence logos for 80 Latimeria T2Rs and 20 Latimeria V1Rs are shown. Letter height indicates the relative frequency with which a particular amino acid appears at that position. Amino acid conservation above 45% is indicated as follows: Latimeria T2Rs, magenta rectangle; Latimeria V1Rs, yellow rectangle; other T2Rs, upper black squares (teleost, left; mouse and frog, right); other V1Rs, lower black squares (teleost, left; mouse and frog, right). White squares and rectangles, no conservation found; asterisk, the same position is differently conserved between Latimeria T2Rs and V1Rs; grey bars, transmembrane domains.
