Component of the CCR4-NOT complex which is one of the major cellular mRNA deadenylases and is linked to various cellular processes including bulk mRNA degradation, miRNA-mediated repression, translational repression during translational initiation and general transcription regulation. Additional complex functions may be a consequence of its influence on mRNA expression (By similarity). Component of the CCR4-NOT complex. No obvious phenotypic change is observed. Belongs to the CNOT11 family.
