Structural basis of eukaryotic transcription termination by the Rat1 exonuclease complex

Nature Communications
The 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

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Topoisomerase IIα promotes activation of RNA polymerase I transcription by facilitating pre-initiation complex formation [PDF]

, 2013
Type II DNA topoisomerases catalyse DNA double-strand cleavage, passage and re-ligation to effect topological changes. There is considerable interest in elucidating topoisomerase II roles, particularly as these proteins are targets for anti-cancer drugs.

Multivalent Role of Human TFIID in Recruiting Elongation Components at the Promoter-Proximal Region for Transcriptional Control

Cell Reports, 2019
Summary: Despite substantial progress in our understanding of the players involved and the regulatory mechanisms controlling the initiation and elongation steps of transcription, little is known about the recruitment of elongation factors at promoter ...

ERK2-topoisomerase II regulatory axis is important for gene activation in immediate early genes

Nature Communications, 2023
The function of the mitogen-activated protein kinase signaling pathway is required for the activation of immediate early genes (IEGs), including EGR1 and FOS, for cell growth and proliferation.

The Dangers of Transcription [PDF]

Cell, 2009
Transcription is obviously essential, but even a good thing can be dangerous at times. In this issue, Lin et al. (2009) provide evidence that binding of the transcription machinery may predispose genome regions to breakage and translocations that may lead to cancer.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

The small genome segment of Bunyamwera orthobunyavirus harbours a single transcription-termination signal [PDF]

, 2012
Transcription termination of the mRNA produced from the small (S) genome segment of Bunyamwera orthobunyavirus (BUNV) has previously been mapped to two cis-acting sequences located within the 5′ UTR using a virus-free replication assay.

Structural insights into the Nipah virus nucleocapsid assembly

Communications Biology
Nipah virus (NiV), a lethal zoonotic henipavirus, poses a major public health threat. Its nucleoprotein (N) safeguards the genome by forming a nucleocapsid, which, together with the RNA-dependent RNA polymerase (L) and phosphoprotein (P), constitutes the

Stability of the PHF10 subunit of PBAF signature module is regulated by phosphorylation: role of β-TrCP

Scientific Reports, 2017
The PBAF chromatin-remodeling complexes are multi-protein machines, regulating expression of genes involved in proliferation and differentiation. PHF10 is a subunit of the PBAF essential for its association with chromatin. Mammalian PHF10 is expressed as
