Ubiquitination and proteasomal degradation of ATG12 regulates its proapoptotic activity [PDF]

, 2014
During macroautophagy, conjugation of ATG12 to ATG5 is essential for LC3 lipidation and autophagosome formation. Additionally, ATG12 has ATG5-independent functions in diverse processes including mitochondrial fusion and mitochondrial-dependent apoptosis.

Proteasome as a Molecular Target of Microcystin-LR

Toxins, 2015
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 ...

A Conditional Yeast E1 Mutant Blocks the Ubiquitin–Proteasome Pathway and Reveals a Role for Ubiquitin Conjugates in Targeting Rad23 to the Proteasome [PDF]

, 2007
E1 ubiquitin activating enzyme catalyzes the initial step in all ubiquitin-dependent processes. We report the isolation of uba1-204, a temperature-sensitive allele of the essential Saccharomyces cerevisiae E1 gene, UBA1.

Inhibition on Proteasome β1 Subunit Might Contribute to the Anti-Cancer Effects of Fangchinoline in Human Prostate Cancer Cells. [PDF]

PLoS ONE, 2015
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

Interplay between RNA Viruses and Promyelocytic Leukemia Nuclear Bodies

Veterinary Sciences, 2021
Promyelocytic leukemia nuclear bodies (PML NBs) are nuclear membrane-less sub structures that play a critical role in diverse cellular pathways including cell proliferation, DNA damage, apoptosis, transcriptional regulation, stem cell renewal ...

The proteasome 19S cap and its ubiquitin receptors provide a versatile recognition platform for substrates

Nature Communications, 2020
Proteins are targeted to the proteasome by the attachment of ubiquitin chains, which are markedly varied in structure. Three proteasome subunits–Rpn10, Rpn13, and Rpn1–can recognize ubiquitin chains. Here we report that proteins with single chains of K48-

Broad activation of the ubiquitin-proteasome system by Parkin is critical for mitophagy [PDF]

, 2011
Parkin, an E3 ubiquitin ligase implicated in Parkinson's disease, promotes degradation of dysfunctional mitochondria by autophagy. Using proteomic and cellular approaches, we show that upon translocation to mitochondria, Parkin activates the ubiquitin ...

The capture proteasome assay (CAPA) to evaluate subtype-specific proteasome inhibitors

Data in Brief, 2015
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.
