While proteasome inhibitors are now well-established research tools and chemotherapeutics, proteasome activators are much less explored. In this issue of Cell Chemical Biology, in a study from the groups of Berkers and Ovaa (Leestemaker et al., 2017), a chemical screen was used to identify a p38 MAPK inhibitor as a proteasome activator.

Phosphatase UBLCP1 controls proteasome assembly [PDF]
Ubiquitin-like domain-containing C-terminal domain phosphatase 1 (UBLCP1), an FCP/SCP phosphatase family member, was identified as the first proteasome phosphatase.

Proteasome as a Molecular Target of Microcystin-LR
Proteasome degrades proteins in eukaryotic cells. As such, the proteasome is crucial in cell cycle and function. This study proved that microcystin-LR (MC-LR), which is a toxic by-product of algal bloom, can target cellular proteasome and selectively ...

Prion diseases are fatal neurodegenerative disorders that include Creutzfeldt-Jakob disease in humans and bovine spongiform encephalopathy in animals. They are unique in terms of their biology because they are caused by the conformational re-arrangement of a normal host-encoded prion protein, PrPC, to an abnormal infectious isoform, PrPSc.

Proteasomes degrade a multitude of protein substrates in the cytosol and nucleus, and thereby are essential for many aspects of cellular function. Because the proteolytic sites are sequestered in a closed barrel-shaped structure, activators are required to facilitate substrate access.

Inhibition on Proteasome β1 Subunit Might Contribute to the Anti-Cancer Effects of Fangchinoline in Human Prostate Cancer Cells. [PDF]
Fangchinoline is a bisbenzylisoquinoline alkaloid isolated from Radix Stephaniae tetrandrae S. Moore. Fangchinoline and its structure analogue, tetrandrine, exhibited direct binding affinity with recombinant human proteasome β1 subunit and also inhibited

SPOP targets the immune transcription factor IRF1 for proteasomal degradation
Adaptation of the functional proteome is essential to counter pathogens during infection, yet precisely timed degradation of these response proteins after pathogen clearance is likewise key to preventing autoimmunity. Interferon regulatory factor 1 (IRF1)

The capture proteasome assay (CAPA) to evaluate subtype-specific proteasome inhibitors
We recently developed a new assay to measure proteasome activity in vitro (CAPA for capture proteasome assay) [1], based on proteasome capture on an antibody-coated plate.

Regulation of TRIB1 abundance in hepatocyte models in response to proteasome inhibition
Tribbles related homolog 1 (TRIB1) contributes to lipid and glucose homeostasis by facilitating the degradation of cognate cargos by the proteasome. In view of the key metabolic role of TRIB1 and the impact of proteasome inhibition on hepatic function ...
