Phylogenetic analysis of myosin heavy chains (MYHs) from Japanese lamprey, torafugu and humans.

<p>The neighbor-joining (A) and maximum-likelihood (B) trees based on the full-length amino acid sequences of fast skeletal MYHs from Japanese lamprey, torafugu and humans. Cardiac and slow skeletal MYHs of torafugu and humans and sarcomeric MYH of bay scallops were used as outgroups. Lc MYHs from the Japanese lamprey <i>Lethenteron camtschaticum</i> were compared with Hs MYH1 (adult fast IId/x), Hs MYH2 (adult fast IIa), Hs MYH8 (perinatal fast), Hs MYH4 (adult fast IIb), Hs MYH3 (embryonic fast), Hs MYH13 (extraocular fast), Hs MYH6 (alpha cardiac), Hs MYH7 (beta cardiac) and Hs MYH14/7B (slow A) from human, <i>Homo sapiens</i>, and Ai MYH (striated muscle) from the bay scallop, <i>Argopecten irradians</i>. MYH sequences of the torafugu, <i>Takifugu rubripes</i> (Tr), were cited from our previous data [16-19].
