Biochem/physiol Actions

MG-132(R) is a potent, membrane-permeable proteasome inhibitor. It induces neurite outgrowth in PC12 cells at 10 M. MG-132(R) blocks cleavage of poly(ADP-ribose) polymerase and apoptosis in thymocytes. However, MG-132(R) also activates c-Jun N-terminal protein kinase (JNK-1), which initiates apoptosis in response to cell stress. Proteasome inhibition induces accumulation of heat shock protein mRNA, activation of heat-shock proteins, and enhanced thermotolerance in various cell types.

The tumor protein p53-inducible nuclear protein 2 (TP53INP2) has been reported to participate in autophagy by interacting with autophagosome-localized autophagy-related protein 8 (Atg8) family proteins, including LC3. Here, we uncover a novel function for TP53INP2 in the autophagic degradation of

Pro-inflammatory cytokines are known to induce endothelial cell autophagy, but the role of autophagy in regulating the expression of pro-inflammatory molecules has not been characterized. We hypothesized that autophagy facilitates expression of endothelial adhesion molecules. TNFα and IL-1β induced autophagy

Synaptotagmin-11 (Syt11) is associated with schizophrenia and Parkinson's disease (PD) and is a critical substrate of parkin, an E3 ubiquitin ligase linked to PD. Previously we reported that Syt11 regulates multiple membrane trafficking pathways in neurons and glia. However, the

Here we explore the relationship between presynaptic homeostatic plasticity and proteasome function at the Drosophila neuromuscular junction. First, we demonstrate that the induction of homeostatic plasticity is blocked after presynaptic proteasome perturbation. Proteasome inhibition potentiates release under baseline conditions but
