Transcription is a highly dynamic process that generates single-stranded DNA (ssDNA) in the genome as ‘transcription bubbles’. Here we describe a kethoxal-assisted single-stranded DNA sequencing (KAS-seq) approach, based on the fast and specific reaction between N 3 -kethoxal and guanines in ssDNA. KAS-seq allows rapid (within 5 min), sensitive and genome-wide capture and mapping of ssDNA produced by transcriptionally active RNA polymerases or other processes in situ using as few as 1,000 cells… 

KAS-seq: genome-wide sequencing of single-stranded DNA by N3-kethoxal-assisted labeling.

The recent study shows that ssDNA signals measured by KAS-seq simultaneously reveal the dynamics of transcriptionally engaged RNA polymerase (Pol) II, transcribing enhancers, RNA Pol I and Pol III activities and potentially non-canonical DNA structures with high analytical sensitivity.

KAS-pipe2: a flexible toolkit for exploring KAS-seq and spKAS-seq data

KAS-pipe2 is presented as a flexible and integrated toolkit to facilitate the analysis and interpretation of KAS-seq data and introduces many novel features, including: calculation of transcriptional indexes, identification of single-stranded transcribing enhancers, and high-resolution mapping of R-loops.

New Chromatin Run-On Reaction Enables Global Mapping of Active RNA Polymerase Locations in an Enrichment-free Manner.

A mutation-based and enrichment-free global chromatin run-on sequencing (mGRO-seq) technique to locate active RNPII sites genome-wide at near-base resolution is reported and holds great promise for the study of single-cell transcriptional activity.

A nuclease- and bisulfite-based strategy captures strand-specific R-loops genome-wide

BisMapR reveals a previously unnoticed feature of active enhancers and provides a tool to systematically examine their mechanisms in gene expression and achieves greater resolution and is faster than existing strand-specific R-loop profiling strategies.

Ligand-induced native G-quadruplex stabilization impairs transcription initiation

A reciprocal genome-wide regulation between native G4 dynamics and gene transcription is revealed, which will deepen the understanding of G4 biology toward therapeutically targeting G4s in human diseases.

Genome-wide mapping of G-quadruplex structures with CUT&Tag

The use of Cleavage Under Targets and Tagmentation (CUT&Tag) for mapping native G4 in mammalian cell lines at high resolution and low background and demonstrates the genome-wide co-occurence of single-stranded DNA, G4s and R loops, suggesting an intricate relationship between transcription and non-canonical DNA structures.

BisMapR: a strand-specific, nuclease-based method for genome-wide R-loop detection

BisMapR reveals a previously unnoticed feature of active enhancers and provides a tool to systematically examine their mechanisms in gene expression, and achieves greater resolution and is faster than existing strand-specific R-loop profiling strategies.

Chromophore-assisted proximity labeling of DNA reveals chromosomal organization in living cells.

A novel proximity-dependent DNA labeling method based on the chromophore-assisted nucleobase photooxidation that achieves blue light-activated labeling of local DNA with a bioorthogonal functional handle and is generally applicable for the genome-wide high-resolution mapping of the spatial chromosome organization in living cells.

Non-B DNA: a major contributor to small- and large-scale variation in nucleotide substitution frequencies across the genome

A comprehensive analysis of nucleotide substitution frequencies at non-B DNA loci within noncoding, non-repetitive genome regions, their ±2 kb flanking regions, and 1-Megabase windows, using human-orangutan divergence and human single-nucleotide polymorphisms highlights the role of non- B DNA in germline mutagenesis with implications to evolution and genetic diseases.

Selection and thermostability suggest G-quadruplexes are novel functional elements of the human genome

The first genome-wide analysis of G4 distribution, thermostability, and selection suggests that purifying selection preserves the sequences of functional G 4s, whereas nonfunctional G4s are too costly to be tolerated in the genome.
