WebPaxilline, a tremorogenic fungal alkaloid, potently inhibits large conductance Ca 2+ - and voltage-activated K + (BK)-type channels, but little is known about the mechanism underlying this inhibition. Here we show that inhibition is inversely dependent on BK channel open probability (Po), and is fully relieved by conditions that increase Po, even … WebJul 1, 2024 · A BK channel blocker paxilline potently suppresses BK-D434G-induced hyperexcitability and effectively mitigates absence seizures in mice. Our study thus uncovered a neuronal mechanism of BK GOF in absence epilepsy and provided the evidence that BK inhibition is a promising therapeutic strategy to mitigate BK GOF …

WebC194A still inhibited BK current and pH 6 solution relieved inhibition (Fig. 2C). However, on switching back to pH 7.4, reinhibition of BK was markedly delayed (Fig. 2 D and E), suggesting that loss of the Cys may have destabilized the structure around the RYGK sequence.
