Ubiquitination is known to be important for endocytosis and lysosomal degradation of aquaporin-2 (AQP2). Ubiquitin (Ub) is covalently attached to the lysine residue of the substrate proteins and activation and attachment of Ub to a target protein is mediated by the action of three enzymes (i.e., E1, E2, and E3). In particular, E3 Ub-protein ligases are known to have substrate specificity. This minireview will discuss the ubiquitination of AQP2 and identification of potential E3 Ub-protein ligases for 1-deamino-8-D-arginine vasopressin (dDAVP)-dependent AQP2 regulation.
