Integrated stress response-induced expression of ATF4 and its transactivation of SOX9 causes aberrant chondrocyte differentiation and skeletal defects which can be alleviated by modulating initiation-factor eIF2α phosphorylation translation control.
Erythroid-enriched BMP2K kinase, in addition to its predicted function in endocytosis, regulates distribution and abundance of COPII assemblies and autophagic degradation through opposing actions of its two splicing variants.
Imaging, quantitative immunoblotting and mass spectrometry reveal that hundreds of surface-expressed neuronal membrane proteins exhibit atypical glycosylation profiles, resulting in changes in protein half-life and synaptic responses.
Prenylation of human oligoadenylate synthetase 1 isoform p46 mediates endomembrane targeting and increases its antiviral activity against positive-strand RNA viruses that utilize the host endomembrane system for replication.
CRISPR/Cas9 genome-wide screens using sterol-sensitive endogenous HMG-CoA reductase (HMGCR) reporter identify the sterol-responsive RNF145 and gp78 as independently responsible for sterol-accelerated degradation of HMGCR, the rate-limiting enzyme of cholesterol biosynthesis.
