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.

Peptidylarginine deiminase 2 suppresses inhibitory {kappa}B kinase activity in lipopolysaccharide-stimulated RAW 264.7 macrophages.

Peptidylarginine deiminases (PADs) are enzymes that convert arginine to citrulline in proteins. In this study, we examined PAD-mediated citrullination and its effect on pro-inflammatory activity in the macrophage cell line RAW 264.7. Citrullination of 45-65-kDa proteins was induced when cells were treated with lipopolysaccharide (LPS; 1 μg/ml). Protein citrullination was suppressed by the intracellular calcium chelator BAPTA/AM (30 μM). LPS ... [more]
