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.

Sig1R protein regulates hERG channel expression through a post-translational mechanism in leukemic cells.
Sig1R (Sigma-1receptor) is a 25-kDa protein structurally unrelated to other mammalian proteins. Sig1R is present in brain, liver, and heart and is overexpressed in cancer cells. Studies using exogenous sigma ligands have shown that Sig1R interacts with a variety of ion channels, but its intrinsic function and mechanism of action remain unclear. The human ether-a-gogo related gene (hERG) encodes a ... [more]
