"In conclusion, the results of the present work indicate that ubiquitylation of hERG1 by the ubiquitin ligase Nedd4-2 is a potentially constitutive physiological mechanism for the regulation of hERG1 c[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

"Further experiments will be needed to confirm these results.In addition, hERG1 channels ubiquitylated by Nedd4-2 appear to be targeted to the proteasomal rather than to the lysosomal pathway, although[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

"As quantified in Fig. 5 B, only Nedd4-2 significantly increased the basal ubiquitylation of hERG1, while Nedd4-2-C801S and the other ubiquitin ligases had no effect."

reach
"These two complementary methods enabled us to confirm that hERG1 was most likely directly ubiquitylated by Nedd4-2, since Nedd4-2 co-expression robustly increased the ubiquitylation of the channel."

"Finally, we determined that Nedd4-2 mediates ubiquitylation of hERG1 and that deletion of this motif affects Nedd4-2-dependent regulation."

reach
"These results suggest that ubiquitylation of the hERG1 protein by Nedd4-2, and its subsequent down-regulation, could represent an important mechanism for modulation of the duration of the human cardiac action potential."
