    Elena Arystarkhova
    Laboratory of Membrane Biology, Massachusetts General Hospital and Harvard Medical School, Boston, Massachusetts, USA
    J Bioenerg Biomembr 37:381-6. 2005
    ..The focus is on splice variants of gamma, their structural similarity and yet distinct effects conferred to Na, K-ATPase...
  2. ncbi request reprint Multiplicity of expression of FXYD proteins in mammalian cells: dynamic exchange of phospholemman and gamma-subunit in response to stress
    Elena Arystarkhova
    Laboratory of Membrane Biology, Massachusetts General Hospital, Boston, MA 02114, USA
    Am J Physiol Cell Physiol 292:C1179-91. 2007
    ..The data imply that FXYDs are obligatory rather than auxiliary components of Na-K-ATPase, and their interchangeability underlies responses of Na-K-ATPase to cellular stress...
  3. ncbi request reprint Distribution and oligomeric association of splice forms of Na(+)-K(+)-ATPase regulatory gamma-subunit in rat kidney

    Laboratory of Membrane Biology, Neuroscience Center, Massachusetts General Hospital, Charlestown, Massachusetts 02129, USA
    Am J Physiol Renal Physiol 282:F393-407. 2002
    ..Because different mechanisms maintain and regulate Na(+) homeostasis in different nephron segments, the splice forms of the gamma-subunit may have evolved to control the renal Na(+) pump through pump properties, gene expression, or both...
