RT Na,K-ATPase in cerebellum and choroid plexus.";
RL J. Neurosci. 23:2161-2169(2003).
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 (By similarity).
CC {ECO:0000250}.
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 -!- 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:0000269|PubMed:12657675}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000250}; Multi-pass membrane
CC protein {ECO:0000250}. Cell membrane {ECO:0000250}; Multi-pass membrane
CC protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the cation transport ATPase (P-type) (TC 3.A.3)
CC family. Type IIC subfamily. {ECO:0000305}.
