NRV1

NRV1 (nervana protein) is β subunit of the Na+/K+ ATPase that differ in their cytoplasmic tails. It has shown that NRV1 is nervous system specific.

nrv1

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 beta subunit regulates, through assembly of alpha/beta heterodimers, the number of sodium pumps transported to the plasma membrane.
