Article thumbnail Anuran Calcitonins are Diverse in Lower Vertebrates

By Hidenori Sakamoto, Yuichi Sasayama and Kunihiko Ueda


ABSTRACT—We investigated the nucleotide sequences of cDNA fragments coding calcitonin from ultimobranchial glands in 2 species of urodelans (1 salamander and 1 newt) and 4 species of anurans (1 toad and 3 frogs) by the reverse transcription polymerase chain reaction (RT-PCR) method and rapid amplifica-tion of cDNA ends (RACE)-PCR method. The salamander and newt calcitonins were each 97 % and 94% similar to the lungfish and caiman calcitonins that we have already reported, in the amino acid sequences. However, anuran calcitonins were not only dissimilar (63–81%) to the lungfish and caiman calcitonins but also diversified (59–91%) even among anurans. The sequence identity of toad calcitonin was always low (59–66%) among anurans
