A & C. Unique nucleotide profile and relative expression of the predicted Rhox2A-H (A) or Rhox4A-H (C) transcripts. The position of the nucleotides is relative to the published start sites. Column RT and EST refers to the number of each transcript detected by RT-PCR or in the EST database respectively that matched this profile. B & D. ClustalW alignment of predicted amino acid sequence from Rhox2A-H (B) or Rhox4A-H (D) Residues different from the consensus are highlighted in blue (conservative amino acid change) or red (non-conservative amino acid change). The homeobox domain is underlined with hydrophobic residues (+) crucial for homeodomain packing and residues involved in DNA binding (*) annotated.
