title: Transcriptional mapping of two yeast genes coding for glyceraldehyde 3-phosphate dehydrogenase isolated by sequence homology with the chicken gene.
abstract: Homology between the coding regions of the chicken and yeast glyceraldehyde 3-phosphate dehydrogenase (GAPDH) genes was directly demonstrated by the hybridization of a cDNA clone coding for GAPDH in the chicken with EcoRI-digested yeast DNA. A yeast EcoRI fragment library in bacteriophage lambda was screened using the chicken cDNA plasmid as probe, and two recombinant phages were isolated, each one containing a different GAPDH gene. The initiation and termination sites for the GAPDH mRNA were localized for the two different GAPDH genes and compared to those of other yeast genes. Measurements of the relative mRNA levels for the two genes show that both genes are transcribed at about the same level when yeasts are grown on glucose media.
