CC -!- FUNCTION: This is the catalytic component of the active enzyme, which
CC catalyzes the hydrolysis of ATP coupled with the exchange of sodium and
CC potassium ions across the plasma membrane. This action creates the
CC electrochemical gradient of sodium and potassium, providing the energy
CC for active transport of various nutrients.
CC {ECO:0000269|PubMed:33880529}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O + K(+)(out) + Na(+)(in) = ADP + H(+) + K(+)(in) +
CC Na(+)(out) + phosphate; Xref=Rhea:RHEA:18353, ChEBI:CHEBI:15377,

CC ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:456216;
CC EC=7.2.2.13;
CC -!- SUBUNIT: The sodium/potassium-transporting ATPase is composed of a
CC catalytic alpha subunit, an auxiliary non-catalytic beta subunit and an
CC additional regulatory subunit. Interacts with regulatory subunit FXYD1.
CC {ECO:0000250|UniProtKB:A2VDL6}.

CC -!- DISEASE: Migraine, familial hemiplegic, 2 (FHM2) [MIM:602481]: A
CC subtype of migraine with aura associated with hemiparesis in some
CC families. Migraine is a disabling symptom complex of periodic
CC headaches, usually temporal and unilateral. Headaches are often
CC accompanied by irritability, nausea, vomiting and photophobia, preceded
CC by constriction of the cranial arteries. Migraine with aura is
CC characterized by recurrent attacks of reversible neurological symptoms
CC (aura) that precede or accompany the headache. Aura may include a
CC combination of sensory disturbances, such as blurred vision,
CC hallucinations, vertigo, numbness and difficulty in concentrating and
CC speaking. {ECO:0000269|PubMed:12539047, ECO:0000269|PubMed:12953268,

CC affecting the gene represented in this entry.
CC -!- DISEASE: Alternating hemiplegia of childhood 1 (AHC1) [MIM:104290]: A
CC rare syndrome of episodic hemi- or quadriplegia lasting minutes to
CC days. Most cases are accompanied by dystonic posturing, choreoathetoid
CC movements, nystagmus, other ocular motor abnormalities, autonomic
CC disturbances, and progressive cognitive impairment. It is typically
CC distinguished from familial hemiplegic migraine by infantile onset and
CC high prevalence of associated neurological deficits that become
CC increasingly obvious with age. {ECO:0000269|PubMed:15174025}. Note=The
CC disease is caused by variants affecting the gene represented in this
CC entry.
CC -!- DISEASE: Fetal akinesia, respiratory insufficiency, microcephaly,
CC polymicrogyria, and dysmorphic facies (FARIMPD) [MIM:619602]: An
CC autosomal recessive disease characterized by fetal akinesia, and
CC generalized joint contractures and arthrogryposis at birth. Affected
CC newborns have severe respiratory insufficiency and significant
CC dysmorphic facial features. Malformations of cortical development are
CC seen on brain imaging, most commonly polymicrogyria or other gyral
CC anomalies. Death usually occurs in infancy.
CC {ECO:0000269|PubMed:30690204, ECO:0000269|PubMed:31608932}. Note=The
CC disease is caused by variants affecting the gene represented in this
CC entry.
CC -!- DISEASE: Developmental and epileptic encephalopathy 98 (DEE98)
CC [MIM:619605]: A form of epileptic encephalopathy, a heterogeneous group
CC of early-onset epilepsies characterized by refractory seizures,
CC neurodevelopmental impairment, and poor prognosis. Development is
CC normal prior to seizure onset, after which cognitive and motor delays
CC become apparent. DEE98 is an autosomal dominant form characterized by
CC onset of seizures in the first decade. {ECO:0000269|PubMed:27864847,
CC ECO:0000269|PubMed:33880529}. Note=The disease is caused by variants
CC affecting the gene represented in this entry.
CC -!- SIMILARITY: Belongs to the cation transport ATPase (P-type) (TC 3.A.3)
CC family. Type IIC subfamily. {ECO:0000305}.
