Identification of the Na/K-ATPase Interacting Proteins

by Jing, Yonghua

Abstract (Summary)
Na,K-ATPase needs to interact with neighboring membrane proteins and organized cytosolic cascades of signaling complexes to function as a signal transducer. The identities of these interacting proteins and the nature of their association with the sodium pump have yet to be elucidated. Some studies have shown that the nucleotide binding domain 1 (ND1) of Na,K-ATPase á1 subunit play an important role when Na,K-ATPase interacts with other proteins. In an attempt to identify novel proteins that can interact with Na,K-ATPase, we used the ND1 domain of sodium pump á1 subunit as a bait to perform a yeast two hybrid screen in a human kidney cDNA library. We have obtained several cDNA clones encoding the potential Na,K-ATPase á1 subunit binding proteins. How these proteins interact with Na,K-ATPase and play a role in Na,K-ATPase mediated signal transduction needs further investigation.
