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.

Regulation of complex formation of POB1/epsin/adaptor protein complex 2 by mitotic phosphorylation.

Kariya K, Koyama S, Nakashima S, Oshiro T, Morinaka K, Kikuchi A

RalBP1 and POB1, the downstream molecules of small GTP-binding protein Ral, are involved in receptor-mediated endocytosis together with Epsin and Eps15. The regulation of assembly of the complex of these proteins was examined. RalBP1, POB1, Epsin, and Eps15 formed a complex with alpha-adaptin of AP-2 in Chinese hamster ovary cells, but the formation was reduced in mitotic phase. RalBP1, POB1, ... [more]

Co-fractionation
Co-fractionation

Interaction inferred from the presence of two or more protein subunits in a partially purified protein preparation. If co-fractionation is demonstrated between 3 or more proteins, then add them as a complex.
