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.

Cysteine desulfurase is regulated by phosphorylation of Nfs1 in yeast mitochondria.

Rocha AG, Knight SAB, Pandey A, Yoon H, Pain J, Pain D, Dancis A

The cysteine desulfurase Nfs1/Isd11 uses the amino acid cysteine as the substrate and its activity is absolutely required for contributing persulfide sulfur to the essential process of iron-sulfur (Fe-S) cluster assembly in mitochondria. Here we describe a novel regulatory process involving phosphorylation of Nfs1 in mitochondria. Phosphorylation enhanced cysteine desulfurase activity, while dephosphorylation decreased its activity. Nfs1 phosphopeptides were identified, ... [more]

Affinity Capture-Western

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 identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.
