Summary
Nonconventional N-methyl-D-aspartate receptors (NMDAR) containing the GluN3A subunit alter receptor function. GluN3A
Area of Science:
- Neuroscience
- Molecular Biology
- Cell Biology
Background:
- N-methyl-D-aspartate receptors (NMDAR) are crucial for synaptic plasticity and memory.
- Conventional NMDARs are heterotetramers of GluN1 and GluN2 subunits.
- GluN3 subunits can form nonconventional NMDARs, altering receptor properties.
Purpose of the Study:
- To review the properties of the GluN3A subunit.
- To discuss the role of GluN3A in neurophysiology.
- To explore the involvement of GluN3A in neurological diseases.
Main Methods:
- Literature review of studies on GluN3A.
- Analysis of GluN3A expression patterns.
- Investigation of GluN3A function in neuronal and glial interactions.
Main Results:
- GluN3A transiently expressed during development.
- GluN3A modifies NMDAR stoichiometry and kinetics.
- GluN3A is found in perisynaptic astrocytes, suggesting a role in neuron-glia communication.
Conclusions:
- GluN3A plays a significant role in fine-tuning neuronal networks.
- Dysregulation of GluN3A may contribute to neurological pathologies.
- GluN3A is strategically positioned for neuron-glia signaling.

4.6K
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...

11.4K
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...

51.6K
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

01:15G Protein-coupled Receptors
14.1K
G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

9.0K
G Protein–Coupled Receptors (GPCRs) are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to various stimuli. GPCRs regulate critical physiological pathways and are excellent drug targets for treating diseases such as diabetes, cancer, obesity, depression, or Alzheimer's. Nearly 35% of approved drugs implement their therapeutic effects by selectively interacting with specific GPCRs.
GPCRs are also called heptahelical,...
