Summary
Molecular modeling reveals distinct ligands for native and modified NMDA-receptor NR1-binding cores. Chiral modified receptors bind aliphatic amino acids, potentially key in age-related diseases.
Area of Science:
- Neuroscience
- Molecular Biology
- Biochemistry
Context:
- The N-methyl-D-aspartate receptor (NMDAR) is crucial for synaptic plasticity and memory.
- Chiral modifications, like non-enzymatic Asn racemization, can alter protein function.
- Understanding ligand binding is vital for therapeutic development.
Purpose:
- To model the native and chiral modified NR1-binding core of the NMDAR.
- To identify the specific amino acid ligands for both receptor forms.
- To explore the potential role of these ligands in age-related pathologies.
Summary:
- Molecular dynamics simulations were used to model the NR1-binding core of the NMDAR.
- Native receptor binding involves Gly, D-Ser, D-Asn, and D-Thr.
- Chiral modified receptor binding is characterized by D-Ala, D-Leu, D-Ile, and D-Pro.
Impact:
- Identifies specific amino acid ligands for native and modified NMDAR NR1-binding cores.
- Suggests that aliphatic non-polar amino acids may be effective ligands for the modified receptor in age-related conditions.
- Provides a foundation for further research into NMDARs in aging and neurological disorders.

01:29The Two-State Receptor Model
The two-state receptor model explains a drug's interaction with receptors, such as G protein-coupled receptors and ligand-gated ion channels, to induce or inhibit a biological response. When no natural ligands are present, a receptor exists in an equilibrium of inactive (Ri) and active (Ra) conformations. The inactive form does not produce a response, while the active form generates a basal effect known as constitutive activity.

01:30Ligand-Gated Ion Channel Receptor: Gating Mechanism
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...
02:40Ligand Binding Sites
Proteins are dynamic macromolecules that carry out a wide variety of essential processes; however, the activities of most proteins depend on their interactions with other molecules or ions, known as ligands.
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...

01:15Cholinergic Receptors: Nicotinic
Nicotinic receptors are ligand-gated ion channels that are activated by acetylcholine and nicotine. Upon activation, they cause a rapid increase in the permeability of cells to K+, Na+, and Ca2+, followed by depolarization and excitation. They are in the autonomic ganglia, skeletal neuromuscular junction, CNS, and adrenal medulla.
There are two types of nicotinic receptors: neuromuscular (NM/NM/N1) and neuronal (NN/NN/N2). The two families differ based on their location and selectivity to...

01:19Ligand-gated Ion Channels
Ligand-gated ion channels are transmembrane proteins with a channel for ions to pass through and a binding site for a ligand. The channel opens only when a ligand attaches to the binding site.
Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that include the...
