Mismatch repair and cancer susceptibility.

Abstract excerpt

Mismatch-repair systems have been identified in organisms ranging from Escherichia coli to humans. They can repair almost all DNA base pair mismatches as well as small insertion/deletion mismatches. Molecular and biochemical analyses have shown that the core components of eukaryotic mismatch-repair systems are highly homologous to their bacterial counterparts. In humans, defects in four mismatch-repair genes have...
