ProteomicsCoalescence of endoplasmic reticulum fragments form a new quality-control compartment in adipocytes
Using a combination of state-of-the-art (ultra-) imaging, biochemical and biophysical techniques, this study not only uncover a new cellular quality-control compartment, but demonstrate a profound cellular adaptation capability and plasticity in dealing with misfolded proteins or protein aggregates ...

ProteomicsThe mechanism to dispose of misfolded proteins in the endoplasmic reticulum of adipocytes
Endoplasmic reticulum (ER)-associated degradation (ERAD) and ER-phagy are two principal degradative mechanisms in the ER; however, the crosstalk between these two pathways and its physiological significance remain unexplored. Here we report that SEL1L-HRD1 ERAD limits autophagy and that, when ERAD i...

ProteomicsProteomic screens of SEL1L-HRD1 ER-associated degradation substrates reveal its vital importance in the biogenesis of glycosylphosphatidylinositol-anchored proteins
The SEL1L-HRD1 protein complex of endoplasmic reticulum (ER)-associated degradation (ERAD) plays indispensable roles for many physiological processes in a substrate-specific manner; however, the nature of endogenous substrates remains largely elusive. Here we have developed a unique proteomics strat...

ProteomicsLactylation of Hdac1 regulated by Ldh prevents the pluripotent-to-2C state conversion
Embryonic stem cells (ESCs) were labeled with heavy isotopes, 13C615N4-arginine (Arg10) and 13C614N2-lysine (Lys6), or light isotopes, 12C614N4-arginine (Arg0) and 12C614N2-lysine (Lys0), respectively, for a total of 7 passages to ensure efficient labeling (>97%). The ESCs labeled with heavy isotope...
