Interactome of chromatin-associated RNA Polymerase II from U2OS cells


ABSTRACT: To determine the interactome of RNA Polymerase II (RNAPII), HA-tagged RPB3 was stably expressed in U2OS cells. The cells were harvested followed by the native stepwise isolation of chromatin-associated RNAPII complexes. HA-RPB3 was immunoprecipitated and interacting proteins analyzed by quantitative mass spectrometry. U2OS cells expressing no HA-tagged protein were used for comparison.

Transcripts produced by RNA polymerase II (RNAPII) are fundamental for cellular responses to environmental changes. It is therefore no surprise that there exist multiple avenues for the regulation of this process. To explore the regulation mediated by RNAPII-interacting proteins, we used a small interfering RNA (siRNA)-based screen to systematically evaluate their influence on RNA synthesis. We identified several proteins that strongly affected RNAPII activity. We evaluated one of the top hits,   ...[more]
