Supplementary Figure 3: RPRD1A interacts with RPRD1B via coiled-coil domain in vitro. Related to Figure 4.
From: RPRD1A and RPRD1B are human RNA polymerase II C-terminal domain scaffolds for Ser5 dephosphorylation
Glutathione-S-transferase (GST) pull-down showing the interactions between GST-tagged RPRD1A and His-tagged RPRD1B, its CID or its coiled-coil domain expressed in E. coli.
