Functional consequences of subunit diversity in RNA polymerases II and V.

Cell reports - 29 Mar 2012

Tan Ek Han, Blevins Todd, Ream Thomas S, Pikaard Craig S

Abstract excerpt

Multisubunit RNA polymerases IV and V (Pol IV and Pol V) evolved as specialized forms of Pol II that mediate RNA-directed DNA methylation (RdDM) and transcriptional silencing of transposons, viruses, and endogenous repeats in plants. Among the subunits common to Arabidopsis thaliana Pols II, IV, and V are 93% identical alternative ninth subunits, NRP(B/D/E)9a and NRP(B/D/E)9b. The 9a and 9b subunit variants are...
