Application
XE-991 has been used as a KCNQ (Kv7.2/7.3) inhibitor to examine whether M-current inhibition affects oxytocin receptor (TGOT) mediated depolarization. It has also been used as an KCNQ inhibitor to study the ionic mechanism responsible for the overshoot/undershoot in membrane potential in mouse cholinergic interneurons (ChIs) in the presence of tetrodotoxin (TTX).
Biochem/physiol Actions
XE-991 is a KCNQ channel blocker.
XE-991 is a KCNQ channel blocker; which is more potent than linopiridine (Cat. No. L-134).

Neuronal L-type voltage-gated calcium channels (LTCCs) are involved in several physiological functions, but increased activity of LTCCs has been linked to pathology. Due to the coupling of LTCC-mediated Ca(2+) influx to Ca(2+)-dependent conductances, such as KCa or non-specific cation channels

Dopamine and glutamate transporters (DAT and GLT-1, respectively) share some biophysical characteristics, as both are secondary active carriers coupled to electrochemical ion gradients. In order to identify common or specific components of their respective proteomes, we performed a proximity labelling

Activation of muscarinic acetylcholine receptors (mAChR) facilitates the induction of synaptic plasticity and enhances cognitive function. In the hippocampus, M(1) mAChR on CA1 pyramidal cells inhibit both small conductance Ca(2+)-activated KCa2 potassium channels and voltage-activated Kv7 potassium channels. Inhibition of
