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.

Calnexin associates exclusively with individual CD3 delta and T cell antigen receptor (TCR) alpha proteins containing incompletely trimmed glycans that are not assembled into multisubunit TCR complexes.

van Leeuwen JE, Kearse KP

Most T lymphocytes express on their surfaces an oligomeric protein complex consisting of clonotypic alpha beta polypeptides associated with invariant CD3-gamma delta epsilon and zeta chains, designated the T cell antigen receptor (TCR) complex. Assembly and intracellular transport of nascent TCR proteins is believed to be assisted by their interaction with the molecular chaperone calnexin, which for certain molecules functions ... [more]

Co-localization

Interaction inferred from two proteins that co-localize in the cell by indirect immunofluorescence only when in addition, if one gene is deleted, the other protein becomes mis-localized. Also includes co-dependent association of proteins with promoter DNA in chromatin immunoprecipitation experiments.
