Postnatal changes in an alpha subunit isoform, alpha(S), of Na+,K(+)-ATPase in the submandibular gland of rats.


The alpha and alpha(+) isoforms of Na+,K(+)-ATPase were isolated from the kidney and brain of rats and purified. Their antisera were raised to analyze the alpha isoforms in rat tissues. We found that the submandibular gland (SMG) contains a new immunoreactive alpha subunit isoform, designated alpha(S) in this report, in addition to alpha identical with… (More)
