| Research Abstract |
Two types of posttranslational modification (phosphorylation and ubiquitination) of water channel aquqaporin-5 (AQP5) were found in mouse salivary gland cells. AQP5 was transiently ubiquitinated and phosphorylated through the stimulation of intracellular Ca^<2+> signaling and the cAMP signaling, respectively. Our present study reveals that the posttranslational modifications of AQP5 are involved in the saliva secretion that is regulated by sympathetic and parasympathetic nervous systems.
