Tritium 212-214 ATP binding cassette subfamily C member 8 Homo sapiens 50-54 30587573-5 2019 We found that ATP binding is sufficient to switch SUR1 alone between inward- or outward-facing conformations with low or high dissociation constant, KD , values for the conformation-sensitive channel antagonist [3H]glibenclamide ([3H]GBM), indicating that ATP can act as a pure agonist. Tritium 231-233 ATP binding cassette subfamily C member 8 Homo sapiens 50-54 30587573-6 2019 Assembly with Kir6.2 reduced SUR1"s KD for [3H]GBM. Tritium 44-46 ATP binding cassette subfamily C member 8 Homo sapiens 29-33 30587573-8 2019 Moreover, ATP/GBM site coupling was constrained in WT SUR1/WT Kir6.2 channels; ATP-bound channels had a lower KD for [3H]GBM than ATP-bound SUR1. Tritium 118-120 ATP binding cassette subfamily C member 8 Homo sapiens 54-58 30587573-8 2019 Moreover, ATP/GBM site coupling was constrained in WT SUR1/WT Kir6.2 channels; ATP-bound channels had a lower KD for [3H]GBM than ATP-bound SUR1. Tritium 118-120 ATP binding cassette subfamily C member 8 Homo sapiens 140-144 12031979-10 2002 [(3)H]glibenclamide binding to membranes from HEK293 cells transfected with SUR1 was displaced by NNC 55-9216 (IC(50) = 105 micromol/l), and this effect was impaired when NBD2 of SUR1 was replaced by that of SUR2A. Tritium 2-5 ATP binding cassette subfamily C member 8 Homo sapiens 76-80 19154434-3 2009 This study investigates the relation between the recovery of channel activity from glibenclamide inhibition and the dissociation rate of [(3)H]-glibenclamide from the channel at 37 degrees C. EXPERIMENTAL APPROACH: K(IR)6.2, K(IR)6.2DeltaN5 or K(IR)6.2DeltaN10 (the latter lacking amino-terminal residues 2-5 or 2-10 respectively) were coexpressed with SUR1 in HEK cells. Tritium 137-143 ATP binding cassette subfamily C member 8 Homo sapiens 353-357 12031979-10 2002 [(3)H]glibenclamide binding to membranes from HEK293 cells transfected with SUR1 was displaced by NNC 55-9216 (IC(50) = 105 micromol/l), and this effect was impaired when NBD2 of SUR1 was replaced by that of SUR2A.
