    motifs/domains
  • a CNOT1 domain interacting with CNOT9, which in turn interacts with the silencing domain of TNRC6 in a tryptophan motif-dependent manner
  • a domain of CNOT1 with an MIF4G fold recruits the DEAD-box ATPase DDX6, a known translational inhibitor
  • CNOT1-Cterminus provides a rigid scaffold consisting of two perpendicular stacks of HEAT-like repeats

    basic FUNCTION
  • may be a negative regulator of transcription
  • represses the ligand-dependent transcriptional activation function of oestrogen receptor (ESR1)
  • contains an intrinsic ability to mediate transcriptional repression
  • has an important role in exhibiting enzymatic activity of the CCR4-NOT complex, and thus is critical in control of mRNA deadenylation and mRNA decay
  • CNOT1, CNOT2, and CNOT3 represent a novel component of the core self-renewal and pluripotency circuitry conserved in Embryonic stem cell (ESC)
  • CNOT1 modulates the conformation of DDX6 and stimulates ATPase activity
  • CNOT1 facilitates recruitment of DDX6 to miRNA-targeted mRNAs, placing DDX6 as a downstream effector in the miRNA silencing pathway

    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • CNOT1 can interact with the ligand-binding domain of ESR1 in a hormone-dependent fashion and is recruited with other Ccr4-Not subunits to endogenous oestrogen-regulated promoters dependent on the presence of ligand
  • CNOT1 interacts in a ligand-dependent manner with RXR and represses transcription mediated by several RXR heterodimers
  • interaction with ZFP36 (ZFP36 directly binds a central domain of CNOT1, a core subunit of the CCR4-NOT complex)
  • DDX6 binds to a conserved CNOT1 subdomain in a manner resembling the interaction of the translation initiation factor EIF4A with EIF4G
  • DDX6 interacts with the CNOT1 complex and functions in concert with several post-transcriptional regulators, including EDC3, and EIF4ENIF1
