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.

A novel molecular mechanism responsible for phosphorylation-independent desensitization of G protein-coupled receptors exemplified by the dopamine D3 receptor.
GRK-mediated receptor phosphorylation followed by association with ?-arrestins has been proposed to be the molecular mechanism involved in the desensitization of G protein-coupled receptors (GPCRs). However, this mechanism does not explain the desensitization of some GPCRs, such as dopamine D3 receptor (D3R), which does not undergo GRK-mediated phosphorylation. Loss-of-function approaches and mutants of dopamine D2 receptor and D3R, which exhibit ... [more]

Additional Notes
- upon immunoprecipition (IP) of G-beta-1, either beta-arrestin1 or beta-arrestin2 was detected by immunoblotting (presumably with an antibody that detects both proteins) in the co-IP
