"The biochemical interactions between hERG1 and Nedd4-2 were investigated by co-immunoprecipitation experiments ( Fig. 3 )."

"As shown in Fig. 3 C, a specific signal for Nedd4-2 was found when ERG1 was immunoprecipitated, thus indicating an interaction between ERG1 and Nedd4-2 in the guinea pig heart."

"It is possible that several PY motifs of hERG1 interact with several WW domains of Nedd4-2 simultaneously.We also demonstrated that WWP2, but not Nedd4-1, interacts with hERG1."

"To confirm the down-regulation of the functional form of hERG1 by Nedd4-2, we quantified the amount of hERG1 localized at the plasma membrane by cell surface biotinylation assays."

"Here, we provide evidence of an interaction between hERG1 and Nedd4-2 in guinea pig hearts, suggesting that ubiquitylation of the channel by this ubiquitin ligase could play a role in its regulation [MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"
