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.

GADD34-PP1c recruited by Smad7 dephosphorylates TGFbeta type I receptor.
The cascade of phosphorylation is a pivotal event in transforming growth factor beta (TGFbeta) signaling. Reversible phosphorylation regulates fundamental aspects of cell activity. TGFbeta-induced Smad7 binds to type I receptor (TGFbeta type I receptor; TbetaRI) functioning as a receptor kinase antagonist. We found Smad7 interacts with growth arrest and DNA damage protein, GADD34, a regulatory subunit of the protein phosphatase ... [more]
