CC -!- FUNCTION: This is the non-catalytic component of the active enzyme,
CC which catalyzes the hydrolysis of ATP coupled with the exchange of
CC Na(+) and K(+) ions across the plasma membrane. The beta subunit
CC regulates, through assembly of alpha/beta heterodimers, the number of
CC sodium pumps transported to the plasma membrane. Plays a role in innate
CC immunity by enhancing virus-triggered induction of interferons (IFNs)
CC and interferon stimulated genes (ISGs). Mechanistically, enhances the
CC ubiquitination of TRAF3 and TRAF6 as well as the phosphorylation of
CC TAK1 and TBK1. {ECO:0000250|UniProtKB:P05026}.
CC -!- FUNCTION: Involved in cell adhesion and establishing epithelial cell
CC polarity. {ECO:0000250|UniProtKB:P05026}.
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 catalytic subunit ATP12A
CC (By similarity). Interacts with regulatory subunit FXYD1 (By
CC similarity). Interacts with regulatory subunit FXYD3 (By similarity).
CC Interacts with NKAIN1, NKAIN2 and NKAIN4 (By similarity). Interacts
CC with MLC1. Part of a complex containing MLC1, TRPV4, AQP4 and HEPACAM.
CC Interacts with KIRREL3 (By similarity). Interacts with OBSCN (via
CC protein kinase domain 1) (By similarity). Interacts with TRAF3 and
CC TRAF6 (By similarity). {ECO:0000250|UniProtKB:P05026,
CC ECO:0000250|UniProtKB:P07340, ECO:0000250|UniProtKB:P14094}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255}; Single-pass type II
CC membrane protein {ECO:0000255}. Apical cell membrane
CC {ECO:0000250|UniProtKB:P07340}; Single-pass type II membrane protein
CC {ECO:0000255}. Cell membrane, sarcolemma
CC {ECO:0000250|UniProtKB:P14094}. Note=Colocalizes with OBSCN at the
CC intercalated disk and sarcolemma in cardiomyocytes. Localizes in long
CC striations at the level of Z and M lines.
CC {ECO:0000250|UniProtKB:P14094}.
CC -!- DOMAIN: The C-terminal lobe folds into an immunoglobulin-like domain
CC and mediates cell adhesion properties. {ECO:0000250}.
CC -!- PTM: Glutathionylated (By similarity). N-glycosylated (By similarity).
CC {ECO:0000250|UniProtKB:P07340, ECO:0000250|UniProtKB:P14094}.
CC -!- SIMILARITY: Belongs to the X(+)/potassium ATPases subunit beta family.
CC {ECO:0000305}.
