Isolation and characterization of a cDNA and a pseudogene for mouse lactate dehydrogenase-A isozyme
Abstract
A mouse lactate dehydrogenase-A cDNA was isolated and it was shown to contain the 393bp of the protein-coding sequence and 488bp of the 3' untranslated region. The amino acid sequence deduced from its open reading frame provided independent evidence for the sequence of residues 201-331 of mouse LDH-A subunit (muscle). This cDNA clone was used as a probe to isolate a mouse genomic clone containing a truncated, processed LDH-A pseudogene. This pseudogene showed 81.6% homology at 713 positions compared with the LDH-A cDNA sequence. The divergence of this pseudogene was estimated to have occurred 39 million years ago.
