Proteasomal degradation of preemptive quality control (pQC) substrates is mediated by an AIRAPL–p97 complex

The initial folding of secreted proteins occurs in the ER lumen, which contains specific chaperones and where posttranslational modifications may occur. Therefore lack of translocation, regardless of entry route or protein identity, is a highly toxic event, as the newly synthesized polypeptide is misfolded and can promiscuously interact with cytosolic factors. Mislocalized proteins bearing a si...

Minimal length requirement for proteasomal degradation of ubiquitin-dependent substrates.

An erroneous transcriptional process, known as molecular misreading, gives rise to an alternative transcript of the ubiquitin B (UBB) gene. This transcript encodes the protein UBB(+1), which comprises a ubiquitin moiety and a 19-aa C-terminal extension. UBB(+1) is found in affected neurons in neurodegenerative diseases and behaves as an atypical ubiquitin fusion degradation (UFD) proteasome sub...

20S proteasomal degradation of ornithine decarboxylase is regulated by NQO1.

Ornithine decarboxylase (ODC), a key enzyme in the biosynthesis of polyamines, is a very labile protein. ODC is a homodimeric enzyme that undergoes ubiquitin-independent proteasomal degradation via direct interaction with antizyme, a polyamine-induced protein. Binding of antizyme promotes the dissociation of ODC homodimers and marks ODC for degradation by the 26S proteasomes. We describe here a...

TLR-dependent Bim phosphorylation in macrophages is mediated by ERK and is connected to proteasomal degradation of the protein.

The pro-apoptotic Bcl-2 homology domain 3-only protein Bim has been shown to play an important role in immune cell homeostasis and various forms of apoptosis in the immune system. Bim is expressed in most immune cells, and regulation of Bim activity can occur on both transcriptional and post-translational levels. Toll-like receptor (TLR) stimulation has previously been shown to increase Bim exp...
