Five muscarinic acetylcholine (mACh) receptor subtypes are divided into two classes: the M1 class (M1, M3, and M5) and the M2 class (M2 and M4). The former is coupled to Gq proteins, while the latter is coupled to Gi/o proteins.

The recurrent excitatory circuits in dlPFC underlying working memory are known to require activation of glutamatergic NMDA receptors (NMDAR). The neurons in these circuits also rely on acetylcholine to maintain persistent activity, with evidence for ...

Opening a hydrophobic gate: the nicotinic acetylcholine receptor as an example [PDF]
To what extent must a hydrophobic gate expand for the channel to count as open? We address this question using the nicotinic acetylcholine receptor (nAChR) as the exemplar. The nAChR is an integral membrane protein which forms a cation selective channel gated by neurotransmitter binding to its extracellular domain.

Systems level circuit model of C. elegans undulatory locomotion: mathematical modeling and molecular genetics [PDF]
To establish the relationship between locomotory behavior and dynamics of neural circuits in the nematode C. elegans we combined molecular and theoretical approaches. In particular, we quantitatively analyzed the motion of C. elegans with defective synaptic GABA and acetylcholine transmission, defective muscle calcium signaling, and defective muscles ...

The surface accessibility of α-bungarotoxin monitored by a novel paramagnetic probe [PDF]
The surface accessibility of {\alpha}-bungarotoxin has been investigated by using Gd2L7, a newly designed paramagnetic NMR probe. Signal attenuations induced by Gd2L7 on {\alpha}-bungarotoxin C{\alpha}H peaks of 1H-13C HSQC spectra have been analyzed and compared with the ones previously obtained in the presence of GdDTPA-BMA. In spite of the different

Predicting novel pharmacological activities of compounds using PubChem IDs and machine learning (CID-SID ML model) [PDF]
Significance and Object: The proposed methodology aims to provide time- and cost-effective approach for the early stage in drug discovery. The machine learning models developed in this study used only the identification numbers provided by PubChem.

Monod-Wyman-Changeux Analysis of Ligand-Gated Ion Channel Mutants [PDF]
We present a framework for computing the gating properties of ligand-gated ion channel mutants using the Monod-Wyman-Changeux (MWC) model of allostery. We derive simple analytic formulas for key functional properties such as the leakiness, dynamic range, half-maximal effective concentration, and effective Hill coefficient, and explore the full spectrum
