Reconstituted Complex

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.

Two phosphorylation-independent sites on the p85 SH2 domains bind A-Raf kinase.

Fang Y, Johnson LM, Mahon ES, Anderson DH

Src homology 2 (SH2) domains mediate phosphotyrosine (pY)-dependent protein:protein interactions involved in signal transduction pathways. We have found that the SH2 domains of the 85-kDa alpha subunit (p85) of phosphatidylinositol 3-kinase (PI3 kinase) bind directly to the serine/threonine kinase A-Raf. In this report we show that the p85 SH2:A-Raf interaction is phosphorylation-independent. The affinity of the p85 C-SH2 domain for ... [more]
