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.

Dual role of BRUCE as an antiapoptotic IAP and a chimeric E2/E3 ubiquitin ligase.

Bartke T, Pohl C, Pyrowolakis G, Jentsch S

Apoptotic cell death and survival is controlled by pro- and antiapoptotic proteins. Because these proteins act on each other, cell fate is dictated by the relative activity of pro- versus antiapoptotic proteins. Here we report that BRUCE, a conserved 528 kDa peripheral membrane protein of the trans-Golgi network, protects cells against apoptosis and functions as an inhibitor of apoptosis (IAP). ... [more]

Biochemical Activity
Biochemical Activity

An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation.

Co-crystal Structure

Interaction directly demonstrated at the atomic level by X-ray crystallography. Also used for NMR or Electron Microscopy (EM) structures. If there is no obvious bait-hit directionality to the interaction involving 3 or more proteins, then the co-crystallized proteins should be listed as a complex.
