FEATURES

FAMILY

X(+)/potassium ATPases subunit beta family

DESCRIPTION

Also known as AT1B2_HUMAN, ATP1B2. This is the non-catalytic component of the active enzyme, which catalyzes the hydrolysis of ATP coupled with the exchange of Na(+) and K(+) ions across the plasma membrane. The exact function of the beta-2 subunit is not known., Mediates cell adhesion of neurons and astrocytes, and promotes neurite outgrowth. The sodium/potassium-transporting ATPase is composed of a catalytic alpha subunit, an auxiliary non-catalytic beta subunit and an additional regulatory subunit. Interacts with isoform 2 of BSG (By similarity).
