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.

The RTP site shared by the HIV-1 Tat protein and the 11S regulator subunit alpha is crucial for their effects on proteasome function including antigen processing.
The human immunodeficiency virus-1 Tat protein inhibits the peptidase activity of the 20S proteasome and competes with the 11S regulator/PA28 for binding to the 20S proteasome. Structural comparison revealed a common site in the Tat protein and the 11S regulator alpha-subunit (REGalpha) called the REG/Tat-proteasome-binding (RTP) site. Kinetic assays found amino acid residues Lys51, Arg52 and Asp67 forming the RTP ... [more]
