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 phosphatidylinositol polyphosphate 5-phosphatase SHIP1 associates with the dok1 phosphoprotein in bcr-Abl transformed cells.

Dunant NM, Wisniewski D, Strife A, Clarkson B, Resh MD

The initial phase of chronic myelogenous leukemia (CML) is triggered by constitutive protein tyrosine kinase activity of the chimeric kinase p210(bcr-abl) (Bcr-Abl). A major substrate of Bcr-Abl was recently identified as the RasGAP-associated 62 kDa docking protein Dok1. Here, we report complex formation between endogenous Dok1 and the SH2 domain-containing phosphatidylinositol polyphosphate 5-phosphatase SHIP1 in hematopoietic cells expressing Bcr-Abl.

Additional Notes

Bcr-Abl induced tyrosine phosphorylation of both Dok1 and SHIP1 and the formation of a Dok1/SHIP1 complex. Tyr(P) SHIP1 was also bound to Shc in Bcr-Abl expressing cells. A small amount of Shc/SHIP1/Dok1 trimolecular complex was detected and this was due

DOK1 RASA1	Reconstituted Complex 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.	Kashige N (2000)	Low	-	BioGRID	-
