The role of deadenylation in the degradation of unstable mRNAs in trypanosomes [PDF]

open access: yesNucleic Acids Research, 2009
Removal of the poly(A) tail is the first step in the degradation of many eukaryotic mRNAs. In metazoans and yeast, the Ccr4/Caf1/Not complex has the predominant deadenylase activity, while the Pan2/Pan3 complex may trim poly(A) tails to the correct size, or initiate deadenylation.

The CCR4–NOT complex maintains liver homeostasis through mRNA deadenylation

open access: yesLife Science Alliance, 2020
The CCR4–NOT complex maintains liver homeostasis by fine-tuning levels of mRNAs, including those for transcription factors, cell cycle regulators, DNA damage response proteins, and liver function–related molecules.

The eIF4E-binding protein Eap1p functions in Vts1p-mediated transcript decay. [PDF]

open access: yesPLoS ONE, 2012
Sequence-specific RNA binding proteins can induce the degradation of mRNAs through their ability to recruit proteins that trigger transcript destabilization. For example, Vts1p, the S.

RNA‐Binding Proteins: Function, Biological Mechanisms, and Therapeutic Opportunities

open access: yesMedComm, Volume 7, Issue 9, September 2026.
RNA‐binding proteins (RBPs) regulate RNA stability, localization, translation, and splicing through intrinsic binding domains and interactions with diverse cellular partners. Their competitive and cooperative networks shape disease‐related RNA programs, especially in cancer.

MicroRNA‐Mediated Placental Maladaptation in Preeclampsia Pathogenesis

open access: yesFASEB BioAdvances, Volume 8, Issue 9, September 2026.
Graphical representation of miRNA‐mediated placental maladaptation in preeclampsia. Under normal pregnancy conditions, balanced expression of beneficial miRNAs (miR‐126‐3p, miR‐18a/b‐5p, miR‐144‐3p, miR‐378a‐5p, and miR‐146a‐5p) promotes trophoblast proliferation, migration and invasion, spiral artery remodeling, angiogenesis, mitochondrial function ...

Dual IRE1 targets: Determinants of the cell fate?

open access: yesThe FEBS Journal, Volume 293, Issue 18, Page 5423-5432, September 2026.
IRE1 is an ER stress sensor that restores protein homeostasis through two signaling activities: XBP1s, which upregulates its target gene expression or RIDD which downregulates its target transcripts. We recently identified Dual IRE1 Targets (DIT) which are modulated by both XBP1s and RIDD activities.

Control of mRNA metabolism by deadenylation

open access: yesThe FASEB Journal, 2013
The presence of a polyadenosine tail is an important determinant of mRNA translation and stability. The regulated removal of the tail, i.e. deadenylation, leads to either translational quiescence or mRNA degradation. Deadenylation, therefore, is a critical node in gene expression and is especially important in certain biological contexts such as in the

The Legionella pneumophila effector PieF modulates mRNA stability through association with eukaryotic CCR4−NOT

open access: yesmSphere
The eukaryotic CCR4−NOT deadenylase complex is a highly conserved regulator of mRNA metabolism that influences the expression of the complete transcriptome, representing a prime target for a generalist bacterial pathogen.

The ApaH-like phosphatase TbALPH1 is the major mRNA decapping enzyme of trypanosomes. [PDF]

open access: yesPLoS Pathogens, 2017
5'-3' decay is the major mRNA decay pathway in many eukaryotes, including trypanosomes. After deadenylation, mRNAs are decapped by the nudix hydrolase DCP2 of the decapping complex and finally degraded by the 5'-3' exoribonuclease. Uniquely, trypanosomes

The RNA‐Binding Protein PARN Remodeled 3′ UTR Structure Defines Poly(A)‐Loading Sites to Mediate Immunoglobulin Homeostasis

open access: yesAdvanced Science, Volume 13, Issue 43, 3 August 2026.
ABSTRACT Class Switch Recombination (CSR) is essential for generating high‐affinity antibody isotypes from IgM during adaptive humoral responses. Despite well‐established roles for various transcription factors, whether CSR is subject to dedicated post‐transcriptional control represents a significant gap in knowledge.
