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.

Pronounced up-regulation of the PA28alpha/beta proteasome regulator but little increase in the steady-state content of immunoproteasome during dendritic cell maturation.

Dendritic cells (DC) are professional antigen-presenting cells that activate CTL by presenting MHC class I-restricted peptides that are processed through the proteasome pathway. Previously, we reported that upon DC maturation the synthesis is switched towards the exclusive production of immunoproteasomes containing the active site subunits LMP2, LMP7 and MECL-1. In this study we investigated the mechanism by which proteasome assembly ... [more]

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.
