The McsB kinase is critical for protein quality control in Gram-positive bacteria, assembling a gated phosphorylation chamber during heat-shock conditions to selectively mark misfolded proteins for degradation.
The human cytomegalovirus (HCMV) interactome systematically characterises high-confidence viral-viral and viral-host protein interactions in HCMV-infected cells, facilitating multiple novel insights into HCMV and herpesviral function.
Proteasomes are protected from autophagic elimination upon carbon starvation by sequestration into cytoplasmic storage granules, which aid cell fitness by providing a cache of proteasomes that can be rapidly remobilized when carbon availability improves.
Mechanical loading and the bone anabolic action of parathyroid hormone result in rapid, lysosomal degradation of sclerostin protein, revealing physiologically important post-translational control of this critical regulator of bone formation.
Under normal nutritional conditions, G-protein coupled receptors can control autophagy by regulating the degradation of key autophagic regulator Atg14L through ZBTB16-mediated ubiquitination and proteasome degradation.
