Fast inhibition and high-affinity activation were decreased by ATP. Therefore peptide activation in the presence of ATP and Mg2+, used with Ca2+ release assays, depends on a mechanism different from that seen when Ca2+ is the sole agonist. The relief of Mg2+ inhibition was particularly important since RyR activation during excitation-contraction coupling depends on a similar decrease in Mg2+ inhibition.]]> Thu 25 Jul 2013 09:09:38 AEST ]]> The mechanism of SR95531 inhibition at GABA(A) receptors examined in human alpha(1)beta(1) and alpha(1)beta(1)gamma(2S) receptors https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:310 Sat 24 Mar 2018 07:42:41 AEDT ]]>
