1 The mutation Kv7.2 R463E increases phosphatidylinositol- 4,5-bisphosphate (PIP2) - channel interaction and diminished dramatically the inhibitory effect of tamoxifen compared with that for wild type Kv7.2. Phosphatidylinositol 4,5-Diphosphate potassium voltage-gated channel subfamily Q member 2 Homo sapiens
2 The mutation Kv7.2 R463E increases phosphatidylinositol- 4,5-bisphosphate (PIP2) - channel interaction and diminished dramatically the inhibitory effect of tamoxifen compared with that for wild type Kv7.2. Phosphatidylinositol 4,5-Diphosphate potassium voltage-gated channel subfamily Q member 2 Homo sapiens
3 Our results suggest that tamoxifen inhibited Kv7.2/Kv7.3 channels by interfering with PIP2-channel interaction because of its documented interaction with PIP2 and the similar effect of tamoxifen on various PIP2 sensitive channels. Phosphatidylinositol 4,5-Diphosphate potassium voltage-gated channel subfamily Q member 2 Homo sapiens
