Extended Data Fig. 6. RNA promotes CDK11 recruitment to the FLASH-containing RDH chromatin.
a, Workflow of nuclear pellet fractionation procedure.
b,c, Western blot analysis of: immunoprecipitates of endogenous FLASH from cell lysates either treated or not with RNase A (b), association of indicated factors in soluble and insoluble fractions of chromatin either treated or not with RNase A/T1 (c) Antibodies are shown on the side of the panels.
d, Western blot analysis of immunoprecipitates of endogenous FLASH from HCT116 cells carrying stably integrated flag-tagged CDK11 (F-CDK11), its indicated deletion mutants and control flag-tagged empty vector (F-EV) (right panel). Western blot analyses of inputs into FLASH immunoprecipitations are shown (left panel). Amounts of flag-tagged CDK11 proteins were monitored by anti-flag antibody.
e, Western blot analysis of endogenous (endo) and flag-tagged CDK11 protein levels in the cells treated with amanitin or triptolide or untreated control (CTRL) used for F-CDK11 ChIP-qPCR (Fig. 4e). Antibodies are shown on the side of the panels.
