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.

Aire's partners in the molecular control of immunological tolerance.

Abramson J, Giraud M, Benoist C, Mathis D

Aire induces the expression of a battery of peripheral-tissue self-antigens (PTAs) in thymic stromal cells, promoting the clonal deletion of differentiating T cells that recognize them. Just how Aire targets and induces PTA transcripts remains largely undefined. Screening via Aire-targeted coimmunoprecipitation followed by mass spectrometry, and validating by multiple RNAi-mediated knockdown approaches, we identified a large set of proteins that ... [more]
