    Scientific background

    Aquaporin 3 (AQP-3) belongs to a family of membrane proteins that allow the passage of water and certain other solutes through biological membranes. The family is composed of 13 members (AQP-0 to AQP-12).

    The aquaporins can be divided into two functional groups based on their permability characteristics: the aquaporins that are only permeated by water and the aquaglyceroporins that are permeated by water and other small solutes such as glycerol. This last group includes AQP-3 as well as AQP-7AQP-9 and AQP-10.1 Little is known about the function of the two newest members, AQP-11 and AQP-12.  

    The proteins present a conserved structure of six transmembrane domains with intracellular N- and C-termini. The functional channel is a tetramer but each subunit has a separate pore and therefore the functional channel unit, contains four pores.1

    AQP-3 is widely expressed in several organs with prominent expression found in the skin, colon, lung and kidney. Consistent with a central function of AQP-3 in skin, mice deficient in AQP-3 have reduced skin water content and elasticity compared with wild-type mice, as well as impaired wound healing and epidermal biosynthesis.2 Furthermore, AQP-3 deficient mice were found to be resistant to skin tumor development suggesting a role for this aquaporin in tumorigenesis.3

    Last update: 08/01/2023

    Anti-Aquaporin 3 Antibody (#AQP-003) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot, immunoprecipitation, indirect flow cytometry, and immunohistochemistry applications. It has been designed to recognize the AQP3 channel from rat, human, and mouse samples.
