Protein attributes

Sequence length	279 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	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-3 subunit is not known.
Subunit structure	Composed of three subunits: alpha (catalytic), beta and gamma.
Subcellular location	Cell membrane; Single-pass type II membrane protein. Melanosome. Note: Identified by mass spectrometry in melanosome fractions from stage I to stage IV. Ref.5
Domain	The C-terminal lobe folds into an immunoglobulin-like domain and may mediate cell adhesion properties By similarity.
Sequence similarities	Belongs to the X(+)/potassium ATPases subunit beta family.
