CCR4 NOT Transcription Complex Subunit 10 (CNOT10)

Component of the CCR4-NOT complex at least composed of CNOT1, CNOT2, CNOT3, CNOT8, CNOT9, CNOT10 and TNKS1BP1. 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 transcription. The Ccr4–Not complex is targeted to the coding region of genes in a transcription-dependent manner similar to RNAPII and promotes elongation in vivo. Furthermore, Ccr4–Not interacts directly with elongating RNAPII complexes and stimulates transcription elongation of arrested polymerase in vitro.
