AQP2 / Aquaporin 2

aquaporin 2 (collecting duct)

Forms a water-specific channel that provides the plasma membranes of renal collecting duct with high permeability to water, thereby permitting water to move in the direction of an osmotic gradient.

Gene Name: aquaporin 2 (collecting duct)
Family/Subfamily: Transporter , Aquaporin
Synonyms: AQP2, AQP-CD, ADH water channel, Aquaporin 2 (collecting duct), AQP-2, Aquaporin 2, Aquaporin-CD, Aquaporin-2, Water-channel aquaporin 2, WCH-CD
Target Sequences: NM_000486 NP_000477.1 P41181
