Cdc48/Shp1 participates in dissociation of protein complexes to regulate their activity.

The AAA-ATPase p97/Cdc48 is one of the most abundant proteins in eukaryotes, and owing to its multiple functions, is considered the swiss army knife of cells. Recent findings demonstrate that p97/Cdc48 and its cofactor p47/Shp1 control the heavy metal stress response by active, signal-triggered disassembly of a multisubunit ubiquitin ligase. Here we review this pathway and describe recently achieved mechanistic insight into the role of p47/Shp1 in this process.
