The Ccr4-Not Complex Regulates Skn7 through Srb10 Kinase [PDF]
ABSTRACT The Ccr4-Not complex is a multifunctional regulatory platform composed of nine subunits that controls diverse cellular events including mRNA degradation, protein ubiquitination, and transcription. In this study, we identified the yeast Saccharomyces cerevisiae osmotic and oxidative stress ...

The CCR4 and CAF1 Proteins of the CCR4-NOT Complex Are Physically and Functionally Separated from NOT2, NOT4, and NOT5 [PDF]
The CCR4-NOT complex (1 mDa in size), consisting of the proteins CCR4, CAF1, and NOT1 to NOT5, regulates gene expression both positively and negatively and is distinct from other large transcriptional complexes in Saccharomyces cerevisiae such as SNF/SWI, TFIID, SAGA, and RNA polymerase II holoenzyme.

The multifunctional Ccr4–Not complex directly promotes transcription elongation [PDF]
The Ccr4–Not complex has been implicated in the control of multiple steps of mRNA metabolism; however, its functions in transcription remain ambiguous. The discovery that Ccr4/Pop2 is the major cytoplasmic mRNA deadenylase and the detection of Not proteins within mRNA processing bodies have raised questions about the roles of the Ccr4–Not complex in ...

Differential regulation of mRNA fate by the human Ccr4-Not complex is driven by coding sequence composition and mRNA localization [PDF]
Background Regulation of protein output at the level of translation allows for a rapid adaptation to dynamic changes to the cell’s requirements. This precise control of gene expression is achieved by complex and interlinked biochemical processes that ...

Subunits of the Drosophila CCR4-NOT complex and their roles in mRNA deadenylation [PDF]
The CCR4-NOT complex is the main enzyme catalyzing the deadenylation of mRNA. We have investigated the composition of this complex in Drosophila melanogaster by immunoprecipitation with a monoclonal antibody directed against NOT1.

The Not5 subunit of the ccr4-not complex connects transcription and translation. [PDF]
Recent studies have suggested that a sub-complex of RNA polymerase II composed of Rpb4 and Rpb7 couples the nuclear and cytoplasmic stages of gene expression by associating with newly made mRNAs in the nucleus, and contributing to their translation and ...

Architecture of the ubiquitylation module of the yeast Ccr4-Not complex. [PDF]
The Ccr4-Not complex regulates eukaryotic gene expression at multiple levels, including mRNA turnover, translational repression, and transcription. We have studied the ubiquitylation module of the yeast Ccr4-Not complex and addressed how E3 ligase binds cognate E2 and how it is tethered to the complex.

The CCR4-NOT complex is implicated in the viability of aneuploid yeasts.
To identify the genes required to sustain aneuploid viability, we screened a deletion library of non-essential genes in the fission yeast Schizosaccharomyces pombe, in which most types of aneuploidy are eventually lethal to the cell.

Reconstitution of Targeted Deadenylation by the Ccr4-Not Complex and the YTH Domain Protein Mmi1
SummaryCcr4-Not is a conserved protein complex that shortens the 3′ poly(A) tails of eukaryotic mRNAs to regulate transcript stability and translation into proteins. RNA-binding proteins are thought to facilitate recruitment of Ccr4-Not to certain mRNAs,
