The DNA-polymerase-X family: controllers of DNA quality?
- Synthesis of the genetic material of the cell is achieved by a large number of DNA polymerases. Besides replicating the genome, they are involved in DNA-repair processes. Recent studies have indicated that certain DNA-polymerase-X-family members can synthesize unusual DNA structures, and we propose that these DNA structures might serve as 'flag wavers' for the induction of DNA-repair and/or DNA-damage-checkpoint pathways.
