A bstract : We recently cloned three cDNAs encoding frog aquaporin (AQP‐h1, BAC07470; AQP‐h2, BAC82379; and AQP‐h3, BAC07471) from the ventral pelvic skin of the tree frog, Hyla japonica . The present study demonstrated that Hyla AQP‐h2 was translocated from cytoplasmic pools to the apical plasma membranes of the granular cells in the bladder after antidiuretic hormone stimulation and that Hyla AQP‐h2 and AQP‐h3 behaved similarly in the ventral pelvic skin. Further, we found that terrestrial and tree frogs, but not aquatic and semiterrestrial‐adapted frogs, absorbed water from their ventral pelvic skin by AQP‐h3‐like protein in concert with AQP‐h2‐like protein.
