Abstract
Covalent chemistry coupled with activity-based protein profiling (ABPP) offers a versatile way to discover ligands for proteins in native biological systems. Here, we describe a set of stereo- and regiochemically defined spirocycle acrylamides and the analysis of these electrophilic "stereoprobes" in human cancer cells by cysteine-directed ABPP. Despite showing attenuated reactivity compared to structurally related azetidine acrylamide stereoprobes, the spirocycle acrylamides preferentially liganded specific cysteines on diverse protein classes. One compound termed ZL-12A promoted the degradation of the TFIIH helicase ERCC3. Interestingly, ZL-12A reacts with the same cysteine (C342) in ERCC3 as the natural product triptolide, which did not lead to ERCC3 degradation but instead causes collateral loss of RNA polymerases. ZL-12A and triptolide cross-antagonized one another's protein degradation profiles. Finally, we provide evidence that the antihypertension drug spironolactone─previously found to promote ERCC3 degradation through an enigmatic mechanism─also reacts with ERCC3_C342. Our findings thus describe monofunctional degraders of ERCC3 and highlight how covalent ligands targeting the same cysteine can produce strikingly different functional outcomes.

Abstract
The nucleotide excision repair (NER) system removes a wide range of bulky DNA lesions that cause significant distortions of the regular double helix structure. These lesions, mainly bulky covalent DNA adducts, are induced by ultraviolet and ionizing radiation or the interaction between exogenous/endogenous chemically active substances and nitrogenous DNA bases. As the number of DNA lesions increases, e.g., due to intensive chemotherapy and combination therapy of various diseases or DNA repair impairment, clustered lesions containing bulky adducts may occur. Clustered lesions are two or more lesions located within one or two turns of the DNA helix. Despite the fact that repair of single DNA lesions by the NER system in eukaryotic cells has been studied quite thoroughly, the repair mechanism of these lesions in clusters remains obscure. Identification of the structural features of the DNA regions containing irreparable clustered lesions is of considerable interest, in particular due to a relationship between the efficiency of some antitumor drugs and the activity of cellular repair systems. In this review, we analyzed data on the induction of clustered lesions containing bulky adducts, the potential biological significance of these lesions, and methods for quantification of DNA lesions and considered the causes for the inhibition of NER-catalyzed excision of clustered bulky lesions.

Abstract
Spironolactone (SP) is commonly used for the treatment of heart failure, hypertension, and complications of cirrhosis by antagonizing the mineralocorticoid receptor. However, SP also antagonizes the androgen receptor, and thus SP has also been shown to be effective in the treatment of acne, hair loss, and hirsutism in women. Interestingly, recent drug repurposing screens have identified new and diverse functions for SP as a simulator of tumor immunosurveillance and as an inhibitor of DNA repair and viral infection. These novel pharmacological effects of SP have all been linked to the ability of SP to induce the rapid proteolytic degradation of the xeroderma pigmentosum group B (XPB) protein. XPB is a critical enzymatic component of the multi-subunit complex known as transcription factor II-H (TFIIH), which plays essential roles in both DNA repair and the initiation of transcription. Given the critical functions for XPB and TFIIH in these processes, the loss of XPB by SP could lead to mutagenesis. However, the ability of SP to promote cancer stem cell death and facilitate immune recognition may counteract the negative consequences of SP to mitigate carcinogenic risk. Thus, SP appears to have new and interesting pharmacological effects that may extend its potential uses.

Abstract
Many chromatin remodeling and modifying proteins are involved in the DNA damage response, where they stimulate repair or induce DNA damage signaling. Interestingly, we identified that downregulation of the histone H1 (H1)-interacting protein SET results in increased resistance to a wide variety of DNA damaging agents. We found that this increased resistance does not result from alleviation of an inhibitory effect of SET on DNA repair but, rather, is the consequence of a suppressed apoptotic response to DNA damage. Furthermore, we provide evidence that the histone chaperone SET is responsible for the eviction of H1 from chromatin. Knockdown of H1 in SET-depleted cells resulted in re-sensitization of cells to DNA damage, suggesting that the increased DNA damage resistance in SET-depleted cells is the result of enhanced retention of H1 on chromatin. Finally, clonogenic survival assays showed that SET and p53 act epistatically in the attenuation of DNA damage-induced cell death. Taken together, our data indicate a role for SET in the DNA damage response as a regulator of cell survival following genotoxic stress.This article has an associated First Person interview with the first author of the paper.

Abstract
Transcription-coupled nucleotide excision repair (TC-NER) is a dedicated DNA repair pathway that removes transcription-blocking DNA lesions (TBLs). TC-NER is initiated by the recognition of lesion-stalled RNA Polymerase II by the joint action of the TC-NER factors Cockayne Syndrome protein A (CSA), Cockayne Syndrome protein B (CSB) and UV-Stimulated Scaffold Protein A (UVSSA). However, the exact recruitment mechanism of these factors toward TBLs remains elusive. Here, we study the recruitment mechanism of UVSSA using live-cell imaging and show that UVSSA accumulates at TBLs independent of CSA and CSB. Furthermore, using UVSSA deletion mutants, we could separate the CSA interaction function of UVSSA from its DNA damage recruitment activity, which is mediated by the UVSSA VHS and DUF2043 domains, respectively. Quantitative interaction proteomics showed that the Spt16 subunit of the histone chaperone FACT interacts with UVSSA, which is mediated by the DUF2043 domain. Spt16 is recruited to TBLs, independently of UVSSA, to stimulate UVSSA recruitment and TC-NER-mediated repair. Spt16 specifically affects UVSSA, as Spt16 depletion did not affect CSB recruitment, highlighting that different chromatin-modulating factors regulate different reaction steps of the highly orchestrated TC-NER pathway.

Abstract
Unperturbed transcription of eukaryotic genes by RNA polymerase II (Pol II) is crucial for proper cell function and tissue homeostasis. However, the DNA template of Pol II is continuously challenged by damaging agents that can result in transcription impediment. Stalling of Pol II on transcription-blocking lesions triggers a highly orchestrated cellular response to cope with these cytotoxic lesions. One of the first lines of defense is the transcription-coupled nucleotide excision repair (TC-NER) pathway that specifically removes transcription-blocking lesions thereby safeguarding unperturbed gene expression. In this perspective, we outline recent data on how lesion-stalled Pol II initiates TC-NER and we discuss new mechanistic insights in the TC-NER reaction, which have resulted in a better understanding of the causative-linked Cockayne syndrome and UV-sensitive syndrome. In addition to these direct effects on lesion-stalled Pol II (effects in cis), accumulating evidence shows that transcription, and particularly Pol II, is also affected in a genome-wide manner (effects in trans). We will summarize the diverse consequences of DNA damage on transcription, including transcription inhibition, induction of specific transcriptional programs and regulation of alternative splicing. Finally, we will discuss the function of these diverse cellular responses to transcription-blocking lesions and their consequences on the process of transcription restart. This resumption of transcription, which takes place either directly at the lesion or is reinitiated from the transcription start site, is crucial to maintain proper gene expression following removal of the DNA damage.

Abstract
Eukaryotic transcription-coupled nucleotide excision repair (TC-NER) is a pathway that removes DNA lesions capable of blocking RNA polymerase II (Pol II) transcription from the template strand. This process is initiated by lesion-arrested Pol II and the recruitment of Cockayne Syndrome B protein (CSB). In this review, we will focus on the lesion recognition steps of eukaryotic TC-NER and summarize the recent research progress toward understanding the structural basis of Pol II-mediated lesion recognition and Pol II-CSB interactions. We will discuss the roles of CSB in both TC-NER initiation and transcription elongation. Finally, we propose an updated model of tripartite lesion recognition and verification for TC-NER in which CSB ensures Pol II-mediated recognition of DNA lesions for TC-NER.
