Abstract

We have isolated cDNA clones encoding fast skeletal muscle myosin heavy chains of carp acclimated to 10, 20 and 30 degrees C for over 5 weeks. All clones covered at least the full length of L-meromyosin, the C-terminal part of the myosin molecule, Nucleotide sequence analysis oncDNA clones showed three types of 3' untranslated sequences, demonstrating that carp expresses at least three myosin heavy chain isoforms in fast skeletal muscle in an acclimation-temperature-dependent manner.cDNAs were identified which were the predominant types expressed in 10 degrees C- and 30 degrees C-acclimated fish, as well as an intermediate type present at all acclimation temperatures, Northern blot analysis using probes of three kinds of DNA fragments from the 3' untranslated region of carp acclimated to 10, 20 and 30 degrees C further confirmed the presence of acclimation-temperature-specific isoforms. In addition, it was found that mRNA levels of three isoforms were altered in an acclimation-temperature-dependent manner. When the deduced amino acid sequences of three types of carp L-meromyosin were compared with those of homoiotherms, the 30 degrees C-acclimated type was more similarto those of homoiotherms than was the 10 degrees C-acclimated type.
