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.

The role of Cullin3-mediated ubiquitination of the catalytic subunit of PP2A in TRAIL signaling.

Xu J, Zhou JY, Xu Z, Kho DH, Zhuang Z, Raz A, Wu GS

Protein phosphatase 2A (PP2A) is the major serine-threonine phosphatase that regulates a number of cell signaling pathways. PP2A activity is controlled partially through protein degradation; however, the underlying mechanism is not fully understood. Here we show that PP2A/C, a catalytic subunit of PP2A, is degraded by the Cullin3 (Cul3) ligase-mediated ubiquitin-proteasome pathway. In response to death receptor signaling by tumor-necrosis ...
