Identification of suncus Kiss1 gene. (A) Nucleotide and deduced amino acid sequences of the suncus Kiss1 gene. Predicted sequences of signal peptide, dibasic sequence regions, and Kp-10 are indicated by double underlining, underlining, and shading, respectively. The asterisk indicates a stop codon. (B) Comparison of amino acid sequences of predicted mature kisspeptin in suncus, human, rat, and mouse. Identical and similar amino acid residues are marked with asterisks and dots, respectively. The shaded box shows the Kp-10 region that is especially conserved through the mammalian species.
