- Extra Details:
- G/T mismatch-specific thymine DNA glycosylase (EC 3.2.2.29; UniProt Q13569; also known as hTDG, Thymine-DNA glycosylase) is encoded by the TDG gene (Gene ID 6996) in human. Base excision repair (BER) is initiated by damage-specific DNA glycosylases that recognize and remove aberrant bases by hydrolyzing the N-glycosidic bond, creating an apurinic/apyrimidinic (AP) site. This is followed by an (AP)-endonuclease-catalyzed DNA strand incision 5′ to the AP site, trimming of the 5′ end by an (AP)-lyase or an endonuclease, DNA resynthesis by a DNA polymerase and strand sealing by a DNA ligase. Monofunctional glycosylases have only glycosylase activity, whereas bifunctional glycosylases possess additional AP lyase activity and can therefore convert a base lesion into a single-strand break without the need for a separate AP endonuclease. TDG is a monofunctional DNA glycosylase that excises thymine and uracil from G·T and G·U mismatched oligonucleotide substrates as well as the highly mutagenic adduct 3,N4-ethenocytosine from double-stranded DNA. TDG DNA-binding affinity is regulated by SUMOylation, which dramatically reduces its affinity toward DNA substrate and AP site. Sumoylation also potentiates the stimulatory effect of (AP)-endonuclease (APE1/HAP1) on TDG. Applications: Suitable for use in Immunocytochemistry and Western Blot. Other applications not tested. Recommended Dilutions: Immunocytochemistry: 2.5ug/ml detected Thymine-DNA Glycosylase in A431, HeLa, HUVEC, and NIH/3T3 cells. Western Blot: 1:5000 detected Thymine-DNA Glycosylase in 10ug of HeLa nuclear extract. Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
