Degradation of human exonuclease 1b upon DNA synthesis inhibition.

Abstract

In response to DNA damage, signaling pathways are triggered that either block the cell division cycle at defined transitions (G1-S and G2-M) or slow down progression through the S phase. Nucleases play important roles in DNA synthesis, recombination, repair, and apoptosis. In this study, we have examined the regulation of human exonuclease 1 (hEXO1b). The… (More)
