SFB-tagged(S-protein tag, Flag epitope tag, and streptavidin-binding peptide tag) RNF4 wild-type and CS mutant LC-MSMS


ABSTRACT: To elucidate the role of RNF4 in DNA replication and fork reversal, we performed tandem affinity purification (TAP) using a HEK293T cell line that stably expresses SFB-tagged(S-protein tag, Flag epitope tag, and streptavidin-binding peptide tag) wild-type and CS mutant to isolate proteins that associate with RNF4.

Replication fork reversal occurs via a two-step process that entails reversal initiation and reversal extension. DNA topoisomerase IIalpha (TOP2A) facilitates extensive fork reversal, on one hand through resolving the topological stress generated by the initial reversal, on the other hand via its role in recruiting the SUMO-targeted DNA translocase PICH to stalled forks in a manner that is dependent on its SUMOylation by the SUMO E3 ligase ZATT. However, how TOP2A activities at stalled forks are  ...[more]
