About this Book

Fifteen years have passed since human aquaporin-1 (AQP1) was discovered as the first water channel, facilitating trans-membrane water fluxes. Subsequent years of research showed that the water channel AQP1 was only the tip of an iceberg; the iceberg itself being a super family of membrane proteins that facilitate membrane transport of a large number of water-soluble, small and uncharged compounds in organisms of all kingdoms of life. The book is dedicated to metalloids, a recently discovered group of substrates for a number of specific MIPs in a divers spectrum of organisms. Particular focus is given to the essential boron, the beneficial silicon and the highly toxic arsenic. The book will also report on recent advances that have changed our view on how transport of metalloids through MIPs is integrated into a network of molecular players that together aid in homeostatic processes at the cellular level. Finally, knowledge about the structure of the channels as well as the environmental chemistry of metalloids should help the reader to understand the relation of MIPs and their role in the exchange of metalloids.
