The alpha4 and alpha7 subunits and assembly of the 20S proteasome.

Apcher GS, Maitland J, Dawson S, Sheppard P, Mayer RJ

The detailed mechanism of eukaryotic 20S proteasome assembly is currently unknown. In the present study, we demonstrate that the 20S proteasome subunits alpha4 and alpha7 interact with each other as well as all the alpha-subunits in vivo and in vitro. The N-terminal parts of alpha4 and alpha7 are essential for these newly discovered interactions in vitro. Glycerol gradient centrifugation of ... [more]

Affinity Capture-Western
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.
