Construction and characterization of a plasmid containing complementary DNA to mRNA encoding the N-terminal amino acid sequence of the rat glutathione transferase Ya subunit.

ABSTRACT: Free polyribosomal poly(A)-containing RNA isolated from normal rat liver was used to prepare a complementary DNA plasmid library in the Pst1 site of the plasmid pAT153 . A plasmid pGSTr155 complementary to mRNA coding for a glutathione transferase Ya subunit was selected by differential hybridization in situ and preliminary characterization was performed by hybrid-selected mRNA translation, immunoprecipitation and polyacrylamide-gel electrophoresis of the product synthesized in vitro. The nucleotide sequence of the complementary DNA contained within pGSTr155 was determined and shown to contain a single open reading frame corresponding to the first 129 amino acids of the N-terminus of the Ya subunit and a further 63 nucleotides upstream of the initiating methionine codon.
