The following antibodies were used for immunoblotting and immunoprecipitation: polyclonal anti-ZC3H4 antibody, developed against a purified GST-tagged human ZC3H4 fragment (amino acid residues 1114–1315) in this study; polyclonal anti-WDR82 antibody (kindly provided by the Roeder laboratory); anti-CK2α (10992-1-AP, Proteintech); anti-CK2β (
ab76025, Abcam); anti-SPT5 (A300-869A for immunoblotting; A300-868A for immunoprecipitation, Bethyl Laboratories); anti-RNAPII (
ab26721, Abcam); anti-S5p RNAPII (
ab5131, Abcam); anti-S2p RNAPII (
ab5095, Abcam); anti-β-actin (
TA811000, Origene); anti-phospho-CK2 substrate [(pS/pT)DXE] (8738, Cell Signaling Technology) and anti-FLAG (
