Pol II is composed of 10–12 polypeptides ranging in size from 220 to 7 kDa, depending on the source of purification (11, 12, 13). The subunits of human pol II (or RNA polymerase B) have been defined as RPB1 (220 kDa), RPB2 (140 kDa), RPB3 (33 kDa), RPB4 (18 kDa), RPB5 (28 kDa), RPB6 (19 kDa), RPB7 (27 kDa), RPB8 (17 kDa), RPB9 (14.5 kDa), RPB10alpha (or RPB12, 7.0 kDa), RPB10beta (or RPB10, 7.6 kDa), and RPB11 (14 kDa) (3,11, 12, 13). RPB5, RPB6, RPB8, RPB10alpha, and RPB10beta are shared by all three eukaryotic RNA polymerases, whereas the rest of the RPB components are unique to pol II |

In eukaryotic cells, the RNA polymerase Pol I synthesizes the rRNA precursor, Pol II transcribes mRNAs and small non-coding RNAs (such as small nuclear RNAs), and Pol III produces tRNAs and other small RNAs. Pol I, II and II contain 14, 12 and 17 polypeptide subunits, respectively (Table 1). |
