The CCR4-NOT complex is a multi-subunit poly(A)-specific 3' exoribonuclease that catalyzes the deadenylation of mRNA. In this chapter, we describe procedures to express and purify recombinant Drosophila melanogaster CCR4-NOT. Furthermore, we provide protocols for preparing radioactively labeled RNA substrates and conducting in vitro deadenylation assays.
CCR4-NOT 复合物是一种多亚基聚（A）特异性 3' 外切核酸酶，可催化 mRNA 的去腺苷酸化。在本章中，我们描述了表达和纯化重组果蝇 melanogaster CCR4-NOT 的程序。此外，我们还提供了制备放射性标记 RNA 底物和进行体外去腺苷酸化测定的方案。
