Alignment of predicted amino acid sequences of mouse, rat, and human Sebox proteins. A dash represents an identical amino acid residue, a dot represents the absence of a residue. Conservative amino acid substitutions (according to Fig. 84 in ref. 23) are shown in bold; conservative amino acid replacement families are as follows: G, A, P, S, T; V, M, I, L; F, Y, W; D, E, N, Q; K, R, H; and C. Homeodomains are enclosed in the shaded box.
