Identification of a structural gene for a RNA polymerase II polypeptide in Drosophila melanogaster and mammalian species.

Journal Article (Journal Article)

Using subclones representing 14 kilobase pairs (kb) of DNA from the Drosophila melanogaster RNA polymerase II (EC X-linked genetic locus, RpII, we have identified four poly(A)+ RNA transcripts in adult flies. The DNA encoding only one of these, a 7-kb transcript, cross-hybridized to mammalian DNA. DNA from alpha-amanitin-resistant (AmaR) Chinese hamster ovary (CHO) and human cells was used to transform the temperature-sensitive (TS) RNA polymerase II Syrian hamster mutant TsAF8. The acquisition of the TS+ AmaR RNA polymerase II phenotype was accompanied by the appearance of donor-DNA-specific restriction fragments that cross-hybridize to the D. melanogaster 7-kb transcript DNA. This D. melanogaster DNA and the related DNA detected in mammalian species must therefore be the structural gene for a RNA polymerase II polypeptide.
