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.

Nuclear export of S6K1 II is regulated by protein kinase CK2 phosphorylation at Ser-17.

Ribosomal S6 kinases (S6Ks) are principal players in the regulation of cell growth and energy metabolism. Signaling via phosphatidylinositol 3-kinase and mammalian target of rapamycin pathways mediates the activation of S6K in response to various mitogenic stimuli. The family of S6Ks consists of two forms, S6K1 and -2, that have cytoplasmic and nuclear splicing variants, S6K1 II and S6K1 I, ... [more]

An interaction is inferred between proteins in vitro. This can include proteins in recombinant form or proteins isolated directly from cells with recombinant or purified bait. For example, GST pull-down assays where a GST-tagged protein is first isolated and then used to fish interactors from cell lysates are considered reconstituted complexes (e.g. PUBMED: 14657240, Fig. 4A or PUBMED: 14761940, Fig. 5). This can also include gel-shifts, surface plasmon resonance, isothermal titration calorimetry (ITC) and bio-layer interferometry (BLI) experiments. The bait-hit directionality may not be clear for 2 interacting proteins. In these cases the directionality is up to the discretion of the curator.
