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.

Cytosolic Iron-Sulfur Assembly Is Evolutionarily Tuned by a Cancer-Amplified Ubiquitin Ligase.

Weon JL, Yang SW, Potts PR

The cytosolic iron-sulfur (Fe-S) cluster assembly (CIA) pathway functions to incorporate inorganic Fe-S cofactors into a variety of proteins, including several DNA repair enzymes. However, the mechanisms regulating the CIA pathway are unknown. We describe here that the MAGE-F1-NSE1 E3 ubiquitin ligase regulates the CIA pathway through ubiquitination and degradation of the CIA-targeting protein MMS19. Overexpression or knockout of MAGE-F1 ... [more]

An interaction is inferred between proteins in vitro. This can include proteins in recombinant form or proteins isolated directly from cells with recombinant or purified bait. For example, GST pull-down assays where a GST-tagged protein is first isolated and then used to fish interactors from cell lysates are considered reconstituted complexes (e.g. PUBMED: 14657240, Fig. 4A or PUBMED: 14761940, Fig. 5). This can also include gel-shifts, surface plasmon resonance, isothermal titration calorimetry (ITC) and bio-layer interferometry (BLI) experiments. The bait-hit directionality may not be clear for 2 interacting proteins. In these cases the directionality is up to the discretion of the curator.
