Na+-K+ ATPase or Na-pump ATPase, a member of "P"-type ATPase
superfamily, is characterized by association of multiple isoforms
mainly of it's - and - subunits. At present four different - ( -1,
-2, -3 and -4) and three - ( -1, -2, and -3) isoforms have been
identified in mammalian cells and their differential expressions
are tissue specific. Regulation of Na+-K+ ATPase activity is an
important but a complex process, which involves short-term and
long-term mechanisms. Short-term regulation of Na+-K+ ATPase is
either mediated by changes in intracellular Na+ concentrations that
directly affect the Na+-pump activity or by
phosphorylation/dephosphorylation-mediated by some stimulants
leading to changes in its expression and transport properties. On
the other hand, long-term regulation of Na+-K+ ATPase is mediated
by hormones, such as mineralocorticoids and thyroid hormones, which
cause changes in the transcription of genes of - and - subunits
leading to an increased expression in the level of Na+-pump.
Several studies have revealed a relatively new type of regulation
that involves the association of small, single span membrane
proteins with this enzyme. These proteins belong to the FXYD
family, the members of which share a common signature sequence
encompassing the transmembra ne domain adjacent to the isoform(s)
of - subunits of Na+-K+ ATPase. Considering the extraordinary
importance of Na+-K+ ATPase in cellular function, several
internationally established investigators have contributed their
articles in the monograph entitled "Regulation of Membrane Na+-K+
ATPase" for inspiring young scientists and graduate students to
enrich their knowledge on the enzyme, and we are sure that this
book will soon be considered as a comprehensive scientific
literature in the area of Na+-K+ ATPase regulation in health and
disease.
