Cloning, partial sequencing, and expression of glyceraldehyde-3-phosphate dehydrogenase gene in chick embryonic heart muscle cells.
Two recombinant plasmids containing structural gene sequences of chick embryonic heart glyceraldehyde-3-phosphate dehydrogenase (GAP dehydrogenase) were constructed and characterized. The plasmids pGAP 30 and pGAP 36 have inserts of 1200 and 950 base pairs, respectively. The identity of the clones was established by hybrid-arrested and hybrid-selection translation assays, and by immunoprecipitation of hybrid-selected translation product with GaP dehydrogenase antiserum. Hybridization of labeled pGAP 30 DNA to size-fractionated chick heart poly(A) RNA occurred at the region on the gel corresponding to the mobility of GAP dehydrogenase mRNA. Base sequence analysis of plasmid pGAP 30 and the comparison of the amino acid sequence derived from it with that of pig muscle GAP dehydrogenase revealed that the amino acid sequence of GAP dehydrogenase is strictly conserved between the chick and pig muscle tissues. Expression of GAP dehydrogenase mRNA in developing chick heart cells in cultures was monitored by in situ hybridization. The GAP dehydrogenase mRNA was present in 5-h-old dividing myoblasts, in contrast to mRNAs specific for contractile proteins, which appear late in myoblast development paralleling morphogenetic differentiation of myoblasts into myocytes (Jakowlew, S. B., Khandekar, P., Datta, K., Narula, S. K., Arnold, H. H., and Siddiqui, M. A. Q. (1982) J. Mol. Biol. 156, 673-682).
