Aquaporin 6 (WCH3, hKID, AQP2-like)
Water is a critical component of all living cells. Interestingly, tissue membranes show a great degree of water permeability. Mammalian red cells, renal proximal tubules, and descending thin limb of Henle are extraordinarily permeable to water. Water crosses hydrophobic plasma membranes either by simple diffusion or through a facilitative transport mechanism mediated by special protein “aquaporin”. Over the last decade, genes for several members of aquaporin family have been cloned, expressed, and their distribution studied in many tissues. AQP6 (WCH3 or hKID or AQP2-like; 282aa; 29kD; chromosome 12q13; rat 276 aa) is found only in the kidney with low water permeability. Human AQP6 is alternatively spliced to isoform 2, a 163 aa protein that contains 2 extra internal regions, which leads to translations shift and an early termination, as compared to the 282- aa isoform 1. the isoform 2 contains an identical N-terminal 134-aa and a distinct 29-aa C-terminus. Human AQP6 AQP families of proteins are predicted to contain six transmembrane domains. The N and C-terminus are predicted to be cytoplasmic. AQP6 shows greatest homology with hMIP (48%) and hAQP-2 (52%). It also has similarity with human MIWC (AQP4; 34%), CHIP-28 (AQP1; 38%), and GLIP (AQP3; 22%).
