The Regulatory Properties of the Ccr4–Not Complex
The mammalian Ccr4–Not complex, carbon catabolite repression 4 (Ccr4)-negative on TATA-less (Not), is a large, highly conserved, multifunctional assembly of proteins that acts at different cellular levels to regulate gene expression.

eIF4A2 drives repression of translation at initiation by Ccr4-Not through purine-rich motifs in the 5′UTR [PDF]
Background Regulation of the mRNA life cycle is central to gene expression control and determination of cell fate. miRNAs represent a critical mRNA regulatory mechanism, but despite decades of research, their mode of action is still not fully understood.

Multivalent interactions with CCR4–NOT and PABPC1 determine mRNA repression efficiency by tristetraprolin [PDF]
Tristetraprolin family of proteins regulate mRNA stability by binding to specific AU-rich elements in transcripts. This binding promotes the shortening of the mRNA poly(A) tail, or deadenylation, initiating mRNA degradation.

Roquin proteins downregulate target mRNA expression by recruiting effectors such as the CCR4-NOT deadenylase complex. Here the authors provide molecular details of how Roquin proteins recruit the CCR4-NOT complex to repress the expression of its targets.

The CCR4-NOT complex physically and functionally interacts with TRAMP and the nuclear exosome. [PDF]
BACKGROUND:Ccr4-Not is a highly conserved multi-protein complex consisting in yeast of 9 subunits, including Not5 and the major yeast deadenylase Ccr4.

Ccr4-not regulates RNA polymerase I transcription and couples nutrient signaling to the control of ribosomal RNA biogenesis. [PDF]
Ribosomal RNA synthesis is controlled by nutrient signaling through the mechanistic target of rapamycin complex 1 (mTORC1) pathway. mTORC1 regulates ribosomal RNA expression by affecting RNA Polymerase I (Pol I)-dependent transcription of the ribosomal ...

Regulation of Early Lymphocyte Development via mRNA Decay Catalyzed by the CCR4-NOT Complex
Development of lymphocytes is precisely regulated by various mechanisms. In addition to transcriptional rates, post-transcriptional regulation of mRNA abundance contributes to differentiation of lymphocytes. mRNA decay is a post-transcriptional mechanism

The Ccr4-Not complex interacts with the mRNA export machinery. [PDF]
The Ccr4-Not complex is a key eukaryotic regulator of gene transcription and cytoplasmic mRNA degradation. Whether this complex also affects aspects of post-transcriptional gene regulation, such as mRNA export, remains largely unexplored.
