ABSTRACT
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.
