Involvement of acetylated tubulin in the regulation of Na+,K+ -ATPase activity in cultured astrocytes.
The results presented support the view that the modulation of Na(+),K(+)-ATPase activity in living cells involves the association/dissociation of acetylated tubulin with the enzyme. We found that the stimulation of Na(+),K(+)-ATPase activity by L-glutamate correlates with decreased acetylated tubulin quantity associated with the enzyme. The effect of L-glutamate was abolished by the glutamate transporter inhibitor DL-threo-beta-hydroxyaspartate but was not affected by either specific agonists or antagonists. The effect of L-glutamate seems to be mediated by Na(+) entry resulting from glutamate transport, since the Na(+) ionophore monensin produced stimulation of Na(+),K(+)-ATPase activity with concomitant decrease of acetylated tubulin quantity associated with the enzyme.
