The Schizosaccharomyces pombe cdc6 gene encodes the catalytic subunit of DNA polymerase delta

Mol Gen Genet. 1997 Mar 18;254(1):93-7. doi: 10.1007/s004380050395.

Abstract

The cdc6 mutants of Schizosaccharomyces pombe have been classified as being defective in progression through the G2 phase of the cell cycle. We cloned an S. pombe gene that could complement the temperature-sensitive growth of the cdc6-23 mutant. Unexpectedly, the cloned gene was allelic to pol3, which encodes the catalytic subunit of DNA polymerase delta. Integration mapping confirmed that ccd6 and pol3 are identical. The cdc6-23 mutant carries one amino acid substitution in the conserved N3 region of Pol3.
