Systematic biochemical analysis of somatic missense mutations in DNA polymerase β found in prostate cancer reveal alteration of enzymatic function

Abstract excerpt

DNA polymerase β is essential for short-patch base excision repair. We have previously identified 20 somatic pol β mutations in prostate tumors, many of them missense. In the current article we describe the effect of all of these somatic missense pol β mutations (p.K27N, p.E123K, p.E232K, p.P242R, p.E216K, p.M236L, and the triple mutant p.P261L/T292A/I298T) on the biochemical properties of the polymerase in...
