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.

In this study, we describe a rapid immunoaffinity purification procedure for gel-free tandem mass spectrometry-based analysis of endogenous protein complexes and apply it to the characterization of complexes containing the SRm160 (serine/arginine repeat-related nuclear matrix protein of 160 kDa) splicing coactivator. In addition to promoting splicing, SRm160 stimulates 3'-end processing via its N-terminal PWI nucleic acid-binding domain and is found ... [more]
