Based on LC-MS results from in vivo and HEK293 cell experiments we chose four KV11.1 mutant candidates for further functional analysis. Ablation of the putative PKD phosphorylation site in the mutant S284A increased the maximal current indicating S284 as a main PKD target in KV11.1. |

We have previously shown that the E3 ubiquitin (Ub) ligase Nedd4-2 (neural precursor cell expressed developmentally down-regulated protein 4-2) targets the PY motif of hERG channels to initiate channel degradation. Although both immature and mature hERG channels contain the PY motif, Nedd4-2 selectively mediates the degradation of mature hERG channels. |

A mechanism for the proarrhythmic effects of cisapride (Propulsid): high affinity blockade of the human cardiac potassium channel HERG. cisapride displays specific, high affinity block of the human cardiac K+ channel HERG. It is likely that this interaction underlies the proarrhythmic effects of the drug observed under certain clinical settings. |
