Ccr4-Not complex: the control freak of eukaryotic cells [PDF]

open access: yesCritical Reviews in Biochemistry and Molecular Biology, 2012
The purpose of this review is to provide an analysis of the latest developments on the functions of the carbon catabolite-repression 4-Not (Ccr4-Not) complex in regulating eukaryotic gene expression. Ccr4-Not is a nine-subunit protein complex that is conserved in sequence and function throughout the eukaryotic kingdom.

Building on the Ccr4‐Not architecture

open access: yesBioEssays, 2016
In a recent issue of Nature Communications Ukleja and co‐workers reported a cryo‐EM 3D reconstruction of the Ccr4‐Not complex from Schizosaccharomyces pombe with an immunolocalization of the different subunits. The newly gained architectural knowledge provides cues to apprehend the functional diversity of this major eukaryotic regulator. Indeed, in the

Tex13a Optimizes Sperm Motility via Its Potential Roles in mRNA Turnover

open access: yesFrontiers in Cell and Developmental Biology, 2021
mRNAs have been found to undergo substantial selective degradation during the late stages of spermiogenesis. However, the mechanisms regulating this biological process are unknown. In this report, we have identified Tex13a, a spermatid-specific gene that

The mRNA degradation factor Xrn1 regulates transcription elongation in parallel to Ccr4 [PDF]

open access: yes, 2019
Co-transcriptional imprinting of mRNA by Rpb4 and Rpb7 subunits of RNA polymerase II (RNAPII) and by the Ccr4–Not complex conditions its posttranscriptional fate.

miRNAs as Influencers of Cell-Cell Communication in Tumor Microenvironment [PDF]

open access: yes, 2020
microRNAs (miRNAs) are small noncoding RNAs that regulate gene expression at the posttranscriptional level, inducing the degradation of the target mRNA or translational repression.

Trametinib improves Treg selectivity of anti-CCR4 antibody by regulating CCR4 expression in CTLs in oral squamous cell carcinoma

open access: yesScientific Reports, 2022
Regulatory T-cells (Tregs) play a major role in suppressing anti-tumor immune responses. Mogamulizumab, an anti-CC chemokine receptor type 4 (CCR4) monoclonal antibody, depletes effector Tregs (eTregs). However, the clinical efficacy of mogamulizumab was

CCR4 and CCR7 differentially regulate thymocyte localization with distinct outcomes for central tolerance

open access: yeseLife, 2023
Central tolerance ensures autoreactive T cells are eliminated or diverted to the regulatory T cell lineage, thus preventing autoimmunity. To undergo central tolerance, thymocytes must enter the medulla to test their T-cell receptors (TCRs) for ...

Twin Promotes the Maintenance and Differentiation of Germline Stem Cell Lineage through Modulation of Multiple Pathways

open access: yesCell Reports, 2015
The central question in stem cell regulation is how the balance between self-renewal and differentiation is controlled at the molecular level. This study uses germline stem cells (GSCs) in the Drosophila ovary to demonstrate that the Drosophila CCR4 ...

The Not4 E3 ligase and CCR4 deadenylase play distinct roles in protein quality control. [PDF]

open access: yesPLoS ONE, 2014
Eukaryotic cells control their proteome by regulating protein production and protein clearance. Protein production is determined to a large extent by mRNA levels, whereas protein degradation depends mostly upon the proteasome.

Role of Ccr4-Not complex in heterochromatin formation at meiotic genes and subtelomeres in fission yeast. [PDF]

open access: yes, 2015
BACKGROUND: Heterochromatin is essential for chromosome segregation, gene silencing and genome integrity. The fission yeast Schizosaccharomyces pombe contains heterochromatin at centromeres, subtelomeres, and mating type genes, as well as at small ...
