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.

Elucidation of the interaction proteome of mitochondrial chaperone Hsp78 highlights its role in protein aggregation during heat stress.

Jaworek W, Sylvester M, Cenini G, Voos W

Chaperones of the Hsp100/Clp family represent major components of protein homeostasis, conferring maintenance of protein activity under stress. The ClpB-type members of the family, present in bacteria, fungi, and plants, are able to resolubilize aggregated proteins. The mitochondrial member of the ClpB family in Saccharomyces cerevisiae is Hsp78. Although Hsp78 has been shown to contribute to proteostasis in elevated temperatures, ... [more]
