"Two E3 ubiquitin ligases, Hrd1 and Doa10 are known to mediate the proteasomal degradation of HMG-CoA reductase Hmg2 and squalene epoxidase Erg1 with accumulation of the toxic sterols in cells, but the deubiquitinases (DUBs) involved are unclear."

reach
"Ubiquitin dependent recruitment of membrane proteins to lipid rafts has been described previously 81 and could be involved in the ubiquitin dependent degradation of WT-hERG following extracellular K + -depletion 82."

reach
"Our results show that the ubiquitin ligase Nedd4-2 down-regulates I hERG1 measured in a mammalian cell line."

reach
"We have previously shown that mature hERG channels are degraded by ubiquitin ligase Nedd4-2 via enhanced channel ubiquitination."

reach
"Extracellular K + -depletion and high salt or acidity also triggered Ub dependent degradation of the wild-type HERG channel and LDL receptor, respectively, presumably by conformational destabilization [XREF_BIBR, XREF_BIBR]."
