ATP1A3 Gene - Sodium-Potassium ATPase Alpha 3

🧬 Gene Info
Gene Symbolent-gene-8ccd65fc
FunctionThe Na+/K+-ATPase is an essential electrogenic pump that maintains the resting membrane potential and regulates cellular volume
Ion TransportActive transport of 3 Na+ out and 2 K+ into neurons per ATP hydrolyzed
Membrane PotentialEstablishes and maintains the neuronal resting membrane potential (-70 to -90 mV)
Secondary TransportPowers secondary active transporters including glutamate transporters
Calcium RegulationIndirectly affects calcium homeostasis through Na+/Ca2+ exchangers
Neuronal SignalingCritical for action potential generation and propagation
Neurotransmitter CyclingEssential for Na+-dependent neurotransmitter reuptake
Basal GangliaHigh expression in striatum (caudate/putamen), globus pallidus, substantia nigra
ThalamusHigh expression in thalamic nuclei
BrainstemProminent expression in brainstem nuclei
CerebellumPurkinje cells and deep cerebellar nuclei
[Cortex](/brain-regions/cortex)Layer 5 pyramidal neurons
Basal gangliaVery high expression in striatum and globus pallidus
