Molecular basis for substrate specificity of the Phactr1/PP1 phosphatase holoenzyme
eLife, 2020 PPP-family phosphatases such as PP1 have little intrinsic specificity. Cofactors can target PP1 to substrates or subcellular locations, but it remains unclear how they might confer sequence-specificity on PP1.

Transcription–Replication Coordination
Life, 2022 Transcription and replication are the two most essential processes that a cell does with its DNA: they allow cells to express the genomic content that is required for their functions and to create a perfect copy of this genomic information to pass on to ...

The dual nature of TDC – bridging dendritic and T cells in immunity
FEBS Letters, EarlyView.TDC are hematopoietic cells combining dendritic and T cell features. They reach secondary lymphoid organs (SLOs) and peripheral organs (liver and lungs) after FLT3‐dependent development in the bone marrow and maturation in the thymus. TDC are activated and enriched in SLOs upon viral infection, suggesting that they might play unique immune roles, since

Inhibition of RNA polymerase II transcription in human cells by synthetic DNA-binding ligands [PDF]
, 1998 Sequence-specific DNA-binding small molecules that can permeate human cells potentially could regulate transcription of specific genes. Multiple cellular DNA-binding transcription factors are required by HIV type 1 for RNA synthesis.

Structural basis of eukaryotic transcription termination by the Rat1 exonuclease complex
Nature CommunicationsThe 5´–3´ exoribonuclease Rat1/Xrn2 is responsible for the termination of eukaryotic mRNA transcription by RNAPII. Rat1 forms a complex with its partner proteins, Rai1 and Rtt103, and acts as a “torpedo” to bind transcribing RNAPII and dissociate DNA/RNA

Protocol for analysis of G2/M DNA synthesis in human cells
STAR Protocols, 2021 Summary: G2/M DNA synthesis (G-MiDS) can be observed in one in five G2/M cells in unperturbed conditions by immunofluorescence microscopy. However, little is known of the genomic sites undergoing G-MiDS.

Topic Model Robustness to Automatic Speech Recognition Errors in Podcast Transcripts [PDF]
arXiv, 2021 For a multilingual podcast streaming service, it is critical to be able to deliver relevant content to all users independent of language. Podcast content relevance is conventionally determined using various metadata sources. However, with the increasing quality of speech recognition in many languages, utilizing automatic transcriptions to provide ...

Functional Characteristics of Gene Expression Motifs with Single and Dual Strategies of Regulation [PDF]
Biomed. Phys. Eng. Express, 2 , 025009(2016), 2016 Transcriptional regulation by transcription factors and post-transcriptional regulation by microRNAs constitute two major modes of regulation of gene expression. While gene expression motifs incorporating solely transcriptional regulation are well investigated, the dynamics of motifs with dual strategies of regulation, i.e., both transcriptional and ...

FEBS Letters, EarlyView.In vivo IL‐10 produced by tissue‐resident tolDC is involved in maintaining/inducing tolerance. Depending on the agent used for ex vivo tolDC generation, cells acquire common features but prime T cells towards anergy, FOXP3+ Tregs, or Tr1 cells according to the levels of IL‐10 produced. Ex vivo‐induced tolDC were administered to patients to re‐establish/
