Application

HeLa cells were treated with DBeQ and the effects on in vivo ubiquitination and protein dislocation were studied by live cell imaging.

Biochem/physiol Actions

DBeQ is a potent and specific inhibitor of ATPase p97, an integral component of the ubiquitin-fusion degradation (UFD) pathway. DBeQ inhibits the degradation of ubiquitinated proteins, the endoplasmic reticulum-associated degradation pathway, and autophagosome maturation. The compound also potently inhibits cellular proliferation and induces caspase 3/7 activity and apoptosis.

Inhibition of the proteasome is a widely used strategy for treating multiple myeloma that takes advantage of the heavy secretory load that multiple myeloma cells (MMCs) have to deal with. Resistance of MMCs to proteasome inhibition has been linked to

Misfolded proteins in the endoplasmic reticulum (ER) are dislocated to the cytosol to be degraded by the proteasomes. Various plant and bacterial toxins and certain viruses hijack this dislocation pathway to exert their toxicity or to infect cells. In this

Processing bodies (P-bodies) are ribonucleoprotein complexes involved in post-transcriptional mRNA metabolism that accumulate in cells exposed to various stress stimuli. The treatment of mammary epithelial cells with transforming growth factor-beta (TGF-β), triggers epithelial-mesenchymal transition (EMT), and induces the formation of

Caveolin-1 (Cav1) drives the formation of flask-shaped membrane invaginations known as caveolae that participate in signaling, clathrin-independent endocytosis and mechanotransduction. Overexpression or mutations of Cav1 can lead to its mistrafficking, including its accumulation in a perinuclear compartment previously identified as

Cullin-RING-ubiquitin-ligase (CRL)-dependent ubiquitination of the nuclear factor kappa B (NF-κB) inhibitor IκBα and its subsequent degradation by the proteasome usually precede NF-κB/RelA nuclear activity.
