Functional correlation between the Ser/Thr-phosphorylation of band-3 and band-3-mediated transmembrane anion transport in human erythrocytes.


In human erythrocytes, okadaic acid, a potent inhibitor of certain protein phosphatases, promotes a marked increase of Ser/Thr-phosphorylation of membrane proteins, including band-3 protein. Moreover, okadaic acid also increases the band-3-mediated oxalate transport across the membranes, thus suggesting that this process is regulated by Ser/Thr… (More)
