Polyclonal Rabbit Affinity Purified B IH IC
AQP3, Aquaporin 3, is the third member of the major intrinsic protein family from rat kidney. AQP3 is localized at the basal lateral membranes of collecting duct cells in the kidney. AQP3 appears to exist as a single copy and to comprise 6 exons distributed over 7kb. The AQP3 gene is mapped to 9p21-p12 by fluorescence in situ hybridization. AQP3 works as water-channel. And it facilitates the transport of nonionic small solutes such as urea and glycerol, albeit to a smaller degree. The results suggested that water channels can be functionally heterogeneous and possess water and solute permeation mechanisms.By Western blot analysis and immunofluorescence microscopy of epidermis, Sougrat et al. (2002) showed strong expression of a ~33-kD glycosylated AQP3 protein in keratinocyte plasma membranes, 1 layer below the unstained stratum corneum (SC). AQP3provides a short circuit for water, or water-clamp, between the base of the epidermis and the SC in order to maintain a constant water content and to prevent the formation of a continuous water gradient across the epidermis below the SC.
