motifs/domains	E1-E2 ATPase
	haloacid dehalogenase-like hydrolase domain
	cation transporting ATPase
	C-terminus domain, of the alpha-subunit having a crucial role in the function of the Na+/K+-ATPase and a key impact of Na+ affinity in the pathophysiology of DYT12 (Blanco-Arias 2009)

basic FUNCTION	osmotic balance and cell volume stability
	neuronal receptor (for AGRN) activity
	is a target for phosphorylation and may participate in short term regulation of neuronal function
	role of ATP1A3 in the inhibitory synapse, and potential involvement of inhibitory synaptic dysfunction for the pathophysiology of dystonia
	plays a crucial role in both physiological and pathological conditions in the brain

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

active transport

text	Na+, K+ pump

PATHWAY

metabolism

signaling

a component

complexing with ATP1B3 and maybe others

INTERACTION

DNA

RNA

small molecule	nucleotide,
	ATP

protein	binding to ATP1B3
	interacting with AGRN
	ATP1A3 and ATP1B2 are binding partners of retinoschisin (predominant role of Na/K-ATPase in anchoring retinoschisin to retinal cell surfaces)
	GPNMB promotes glioma growth via ATP1A1, ATP1A2, ATP1A3, ATP1A4
