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.

Refinement of the endogenous epitope tagging technology allows the identification of a novel NRAS binding partner in melanoma.

The NRAS oncoprotein is highly mutated in melanoma. However, to date, no comprehensive proteomic study has been reported for NRAS. Here, we utilized the endogenous epitope tagging (EET) approach for the identification of novel NRAS binding partners. Using EET, an epitope tag is added to the endogenously expressed protein, via modification of its genomic coding sequence. Existing EET systems are ... [more]

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.
