Reconstitution of Human CCR4-NOT Complex from Purified Proteins and an Assay of Its Deadenylation Activity.

We describe protocols to produce and reconstitute an active human CCR4-NOT complex. Individual recombinant subunits are expressed in E. coli or baculovirus-infected insect cells, purified using column chromatography, and reconstituted into a stable complex containing all eight core subunits. In addition, we describe the biochemical assay of deadenylation using the reconstituted complex.
