title: Cloning of mouse carbonic anhydrase mRNA and its induction in mouse erythroleukemic cells.
abstract: Mouse carbonic anhydrase mRNA was detected in poly(A+) RNA of anemic spleens sedimenting as a RNA species at 14 S. Subsequently, poly(A+) RNA (12-16 S) was used as a template for the synthesis of double-stranded cDNA, which was inserted into the PstI site of pBR322 by oligo-dG:dC tailing. A recombinant plasmid containing carbonic anhydrase cDNA was identified by a positive hybridization selection assay and by partial DNA sequencing. Predicted amino acid sequences showed homology with the known sequences of rabbit and human carbonic anhydrase I and II. The clone contained sequences for most of the coding region and 600-700 base pairs at the 3' noncoding region of the mRNA. Hybridization analysis of poly(A+) RNA from uninduced and induced mouse erythroleukemic cells labeled for short and long time periods indicated that induction results in an increase of carbonic anhydrase mRNA in newly synthesized RNA.
