title: Isolation of a cDNA clone for human threonyl-tRNA synthetase: amplification of the structural gene in borrelidin-resistant cell lines.
abstract: A cDNA for threonyl-tRNA synthetase was isolated from a human placental cDNA lambda gt11 expression library by immunological screening, and its identity was confirmed by hybrid-selected mRNA translation. With this cDNA used as a hybridization probe, borrelidin-resistant Chinese hamster ovary cells that overproduced threonyl-tRNA synthetase were shown to have increased levels of threonyl-tRNA synthetase mRNA and gene sequences. Amplification of the gene did not appear to have been accompanied by any major structural reorganizations.
