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.

Phosphorylation of key serine residues is required for internalization of the complement 5a (C5a) anaphylatoxin receptor via a beta-arrestin, dynamin, and clathrin-dependent pathway.
The human complement 5a (C5a) anaphylatoxin receptor (CD88) is a G protein-coupled receptor involved in innate host defense and inflammation. Upon agonist binding, C5a receptor (C5aR) undergoes rapid phosphorylation on the six serine residues present in the C-terminal region followed by desensitization and internalization. Using confocal immunofluorescence microscopy and green fluorescent protein-tagged beta-arrestins (beta-arr 1- and beta-arr 2-EGFP) we show ... [more]
