CNOT4 Proteins

Protein Information

CNOT4 is a 575 amino acid protein with E3 ubiquitin ligase activity, mainly involved in protein modification and protein ubiquitination. It contains a ring type zinc finger domain of the C4C4 type, an RNA recognition motif and a bipartite nuclear localization signal.Studies show that CNOT4 is a component of the CCR4-NOT (CAF1) core complex that functions as general transcription regulation complex and has both a positive as well as a negative effect on the transcription of multiple functionally unrelated genes, thus controls gene expression. CNOT4 interacts with CNOT1 via C-terminus and with E2 ubiquitin ligases via C4C4 RING domain. Reports suggest that CNOT4 gets phosphorylated in response to DNA damage on consensus sites recognized by ATM and ATR.
