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 JNK-interacting protein-1 scaffold protein targets MAPK phosphatase-7 to dephosphorylate JNK.

Willoughby EA, Perkins GR, Collins MK, Whitmarsh AJ

The c-Jun N-terminal kinase (JNK) group of mitogen-activated protein kinases (MAPKs) are activated by pleiotropic signals including environmental stresses, growth factors, and hormones. A subset of JNK can bind to distinct scaffold proteins that also bind upstream kinases of the JNK pathway, allowing sequential kinase activation within a signaling module. The JNK-interacting protein-1 (JIP-1) scaffold protein specifically binds JNK, MAP ... [more]
