USP29 Rabbit Polyclonal Antibody

The DNA damage checkpoint is essential for the maintenance of genome integrity after genotoxic stress, and also for cell survival in eukaryotes. Claspin has a key role in the ATR (ATM and Rad3-related)-Chk1 branch of the DNA damage checkpoint and is also required for correct DNA replication. To achieve properly these functions, Claspin is tightly regulated by ubiquitinin-dependent proteasomal degradation, which controls Claspin levels in a DNA-damage- and cell-cycle-dependent manner. USP29 is a regulator of Claspin, USP29 is a player in the ATR-Chk1 pathway and the control of DNA replication.
