... aquaporins:aquaporins, AQP0, 1, 2, 4, 5, 8 and 10, selective for water; aquaglyceroporins, AQP3, 7 and 9, with slightly lessselective pores, permeated by water, glycerol and othersmall nonelectrolytes. ... AQP4 and AQP5, arepresent in mammalian lung [14]. AQP4 is unusual amongaquaporins in that water transport is not inhibited byHg2+[15], it has a high intrinsic water permeability [16], and ... the putative water channel cDNA cloned from a female mosquitoMalpighian tubule library [22] and expressed in tracheolarcells encodes an aquaporin and not an aquaglyceroporin, and forms orthogonal...
