The Human IL-22 Receptor Is Regulated through the Action of the Novel E3 Ligase Subunit FBXW12, Which Functions as an Epithelial Growth Suppressor by Joseph Franz, Jacob Jerome, Travis Lear, Qiaoke Gong, Nathaniel M. Weathington

“…We recently described processing of mouse lung epithelial IL-22 receptor (IL-22R) by ubiquitination on the intracellular C-terminal. To identify cellular factors that regulate human IL-22R, we screened receptor abundance while overexpressing constituents of the ubiquitin system and identify that IL-22R can be shuttled for degradation by multiple previously uncharacterized F-box protein E3 ligase subunits. …”

Enhancing proteasome activity by NMDAR antagonists explains their therapeutic effect in neurodegenerative and mental diseases by Fikret Sahin, Aslihan Gunel, Buse Turegun Atasoy, Ulku Guler, Bekir Salih, Isinsu Kuzu, Mehmet Taspinar, Ozgur Cinar, Selda Kahveci

“…Furthermore, the altered proteins exhibited enrichment in terms related to plasticity and potentiation, including retrograde endocannabinoid signaling—a pivotal pathway in both short- and long-term plasticity that may elucidate the long-lasting effects of ketamine in major depression. Via the ubiquitin-independent 20S proteasome pathway (UIPS), these drugs maintain cellular protein homeostasis, which is crucial as proteasome activity declines with age, leading to protein aggregation and disease symptoms. …”

Targeting MDM2 affects spastin protein levels and functions: implications for HSP treatment by Francesca Sardina, Federica Polverino, Sonia Valentini, Claudia Carsetti, Elisabetta Falvo, Giada Tisci, Silvia Soddu, Fabiola Moretti, Alessandro Paiardini, Cinzia Rinaldo

“…By biochemical and functional experiments, we demonstrate that MDM2 binds spastin and regulates its levels in a post-transcriptional manner independently of the E3 ubiquitin ligase activity. Of relevance, treatment of spastin-deficient cells with the MDM2 inhibitor Nutlin-3a can restore spastin levels and functions, such as cytokinetic abscission and sorting of transferrin receptor. …”
