Rev1 is a base excision repair enzyme with 5′-deoxyribose phosphate lyase activity
Rev1 is a member of the Y-family of DNA polymerases and is known for its deoxycytidyl transferase activity that incorporates dCMP into DNA and its ability to function as a scaffold factor for other Y-family polymerases in translesion bypass events. Rev1 also is involved in mutagenic processes during somatic hypermutation of immunoglobulin genes. In light of the mutation pattern consistent with ...
متن کاملIdentification of 5'-deoxyribose phosphate lyase activity in human DNA polymerase gamma and its role in mitochondrial base excision repair in vitro.
Mitochondria have been proposed to possess base excision repair processes to correct oxidative damage to the mitochondrial genome. As the only DNA polymerase (pol) present in mitochondria, pol gamma is necessarily implicated in such processes. Therefore, we tested the ability of the catalytic subunit of human pol gamma to participate in uracil-provoked base excision repair reconstituted in vitr...
متن کاملHuman DNA polymerase θ possesses 5′-dRP lyase activity and functions in single-nucleotide base excision repair in vitro
DNA polymerase theta (Pol theta) is a low-fidelity DNA polymerase that belongs to the family A polymerases and has been proposed to play a role in somatic hypermutation. Pol theta has the ability to conduct translesion DNA synthesis opposite an AP site or thymine glycol, and it was recently proposed to be involved in base excision repair (BER) of DNA damage. Here, we show that Pol theta has int...
متن کاملA target-activated autocatalytic DNAzyme amplification strategy for the assay of base excision repair enzyme activity.
Based on a target-activated autocatalytic DNAzyme amplification strategy, novel fluorescence sensing platforms were constructed for highly sensitive and selective assay of base excision repair enzyme activity. By using a rolling circle amplification (RCA)-coupled amplification cascade, an extremely low detection limit (0.002 U mL(-1)) was achieved.
متن کاملDetection of base excision repair enzyme activity using a luminescent G-quadruplex selective switch-on probe.
We report herein a simple and convenient luminescent assay for detection of base excision repair enzyme activity using an Ir(III) complex as a G-quadruplex selective probe. Using uracil-DNA glycosylase (UDG) as a model enzyme, the assay achieved high sensitivity and selectivity for UDG over other tested enzymes. The utility of the assay for screening potential UDG inhibitors was also demonstrated.
