HSJ1 is a neuronal shuttling factor for the sorting of chaperone clients to the proteasome.

Westhoff B, Chapple JP, van der Spuy J, Hoehfeld J, Cheetham ME

Protein degradation in eukaryotic cells usually involves the attachment of a ubiquitin chain to a substrate protein and its subsequent sorting to the proteasome. Molecular mechanisms underlying the sorting process only recently began to emerge and rely on a cooperation of chaperone machineries and ubiquitin-chain recognition factors [1-3]. Here, we identify isoforms of the cochaperone HSJ1 as neuronal shuttling factors ... [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.
