Wang group solved the CryoEM structure of Pol II-Rad 26 complex and elucidated the structural basis of initiation of eukaryotic transcription-coupled DNA repair.

The Wang group solved the crystal structure of Pol II in complex with 5-carboxylcytosine (5caC) and revealed how Poll II recognizes subtle changes in DNA sequence and structure.

Using an acyclic synthetic RNA analogue, the Wang group demonstrated that the contribution of the intact nucleotide sugar bakbone to the enzymatic efficiency and transcriptional fidelity of RNA polymerase II is significantly stronger than that of the other functional groups of the nucleotide, including the nucleobase and ribose 2'-OH group.

The Wang group designed and constructed a chemical probe, consisting of an aldehyde-targeting group and an intercalation group, that can selectively react with 5-formylcytosine (5fC) and subsequently inhibit base excision by thymine DNA glycosylase (TDG) and cause significant pausing for both DNA and RNA polymerase elongation. Further investigation using a GFP reporter system in living cells revealed that the covalent modification in 5fC sites at 5'-UTR of the GFP gene greatly inhibited the GFP expression level.

The Wang group present the first systematic mechanistic investigation that addresses how a site-specific phenanthriplatin-DNA d(G) monofunctional adduct affects the Pol II elongation and transcriptional fidelity checkpoint steps, which is an important step toward elucidating the mechanism of action of phenanthriplatin.

The Wang group reported the structure of a transcribing RNA polymerase II (Pol II) complex stalled at a site-specific monofunctional pyriplatin-DNA adduct in the active site. The results reveal a molecular mechanism of Pol II transcription inhibition and drug action that is dramatically different from transcription inhibition by cisplatin and UV-induced 1,2-intrastrand cross-links. Our findings provide insight into structure-activity relationships that may apply to the entire family of monofunctional DNA-damaging agents and pave the way for rational improvement of monofunctional platinum anticancer drugs.
