Scientific background

Aquaporin 7 (AQP-7) belongs to a family of membrane proteins that allow passage of water and certain other solutes through biological membranes. The family is composed of 13 members (AQP-0 to AQP-12). Little is known about the function of the two newest members, AQP-11 and AQP-12.

The aquaporins can be divided into two functional groups based on their permeability 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-7, AQP-3, AQP-9 and AQP-10.

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.

AQP-7 is expressed in ovary, testis, kidney and adipose tissue.

The function of AQP-7 in adipose tissue attracted much interest as mice deficient in AQP-7 developed adult-onset obesity and Type 2 Diabetes. AQP-7 modulates adipocyte glycerol permeability thereby controlling triglyceride accumulation and fat cell size.

Last update: 20/10/2021

Anti-Aquaporin 7 Antibody (#AQP-007) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot, immunocytochemistry, and immunohistochemistry applications. It has been designed to recognize AQP-7 from mouse and rat samples, and may recognize the channel from human samples.
