A cDNA clone, labeled pFOD5, isolated from a fetal-rat skeletal-muscle cDNA library, has been characterized and found to contain sequences corresponding to a perinatal-specific skeletal myosin heavy-chain (MHC) mRNA. This MHC cDNA demonstrates a high degree of nucleotide- and amino acid-sequence conservation with other MHC genes, but its carboxyl-terminal peptide and 3'-untranslated region are highly divergent and specific for this gene. S1 nuclease mapping experiments have shown that the perinatal MHC gene represented by this cDNA clone is only transiently expressed during skeletal-muscle development. Perinatal MHC mRNA is first detected late in fetal life, reaches maximal levels of expression at the end of the first postnatal week, and is de-induced thereafter. Its levels are almost undetectable at 28 days of postnatal life. During fetal and early postnatal life, the expression of this perinatal gene in skeletal muscle overlaps with the expression of the embryonic MHC gene. After the first week of extrauterine life, this gene is coexpressed with two adult MHC genes. The transient expression of this perinatal MHC gene raises interesting questions about the physiological significance of the MHC transitions and offers an interesting model for the study of MHC gene regulation.
