CTIP2 and SATB2 predicted proteins share remarkable conservation of functional domains between eutherians and marsupials. (A and B) Functional domain representations, lineage analyses, and three-dimensional (3D) structure predictions of CTIP2 (A; six functional domains) and SATB2 (B; three functional domains) between mouse (MM) and dunnart (DU). (C and D) Sequences of the predicted functional domains for three eutherian and three marsupial species for CTIP2 (C) and SATB2 (D). Asterisk indicates predicted amino acid substitution. CA, dog; CH, chicken; HU, human; KO, koala; OP, opossum; PL, platypus; ZE, zebrafish.
