In unstressedcells, p53 is maintained at low levels by the ubiquitin-proteasome pathway.

In this study, we demonstrate that IRE1a interacts with BiP in unstressedcells and dissociates from BiP in the course of cartilage development.
3
In unstressedcells, DnaK localizes to multiple, dynamic foci, but relocalizes to focal protein aggregates during stationary phase or upon expression of aggregating peptides.
4
This effect is mirrored by enhanced p53 protein levels in both unstressedcells and cells exposed to p53-activating stress agents.

These data indicate that JFK is a critical negative regulator of p53 and represents a pathway for the maintenance of p53 levels in unstressedcells.
