Affinity Capture-MS

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

A RECQ5-RNA polymerase II association identified by targeted proteomic analysis of human chromatin.

Ayguen O, Svejstrup J, Liu Y

Although the active forms of factors involved in DNA-related processes such as DNA replication, repair, and transcription are associated with chromatin, proteins are rarely purified from this source. Here, we describe a protocol for the isolation of chromatin-associated factors and use it to identify proteins interacting with human RNA polymerase II (RNAPII). Our data establish RECQ5 helicase as a bona ... [more]
