Abstract

Despite the highly conserved helicase core, individual DEAD-box proteins are specialized in diverse RNA metabolic processes. One mechanism that determines DEAD-box protein specificity is enzymatic regulation by other protein cofactors. In this chapter, we describe a protocol for purifying the Saccharomyces cerevisiae DEAD-box RNA helicase Dbp2 and RNA-binding protein Yra1 and subsequent analysis of helicase regulation. The experiments described here can be adapted to other RNA helicases and their purified cofactor(s).
