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 ions, providing the
CC energy for active transport of various nutrients.
CC {ECO:0000250|UniProtKB:P05023}.
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:15378, ChEBI:CHEBI:29101, ChEBI:CHEBI:29103,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:456216;
CC EC=7.2.2.13;
CC -!- ACTIVITY REGULATION: Specifically inhibited by cardiac glycosides such
CC as digoxin or ouabain.
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 Interacts with regulatory subunit FXYD3. Interacts with SIK1. Interacts
CC with SLC35G1 and STIM1. Interacts with CLN3; this interaction regulates
CC the sodium/potassium-transporting ATPase complex localization at the
CC plasma membrane (By similarity). {ECO:0000250|UniProtKB:P05023,
CC ECO:0000250|UniProtKB:P06685}.
CC -!- SUBCELLULAR LOCATION: Basolateral cell membrane
CC {ECO:0000250|UniProtKB:P06685}; Multi-pass membrane protein
CC {ECO:0000255}. Cell membrane, sarcolemma
CC {ECO:0000250|UniProtKB:P05023}; Multi-pass membrane protein
CC {ECO:0000255}. Cell projection, axon {ECO:0000250|UniProtKB:P06685}.
CC Melanosome {ECO:0000250|UniProtKB:P05023}.
CC -!- PTM: Phosphorylation on Tyr-10 modulates pumping activity.
CC Phosphorylation of Ser-941 by PKA modulates the response of ATP1A1 to
CC PKC (By similarity). Dephosphorylation by protein phosphatase 2A (PP2A)
CC following increases in intracellular sodium, leading to increase
CC catalytic activity (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the cation transport ATPase (P-type) (TC 3.A.3)
CC family. Type IIC subfamily. {ECO:0000305}.
