Nucleotide and deduced amino acid sequences and phylogenetic tree of caMC4R. (A) Nucleotide and deduced amino acid sequences of caMC4R. Positions of nucleotide and amino acid sequences are indicated on both sides. Shaded boxes denote putative TMD1-7. Potential phosphorylation sites are present in oval frame. Underline show PMY, DRY, DPxxY motifs. Open boxes denote the consensus sequence for N-linked glycosylation sites. Asterisk (*) indicates stop codon. (B) Phylogenetic tree of MC4R proteins. The tree was constructed by the neighbor-joining (NJ) method. Numbers at nodes indicate the bootstrap value, as percentages, obtained for 1,000 replicates. Black dot shows caMC4R.
