Putative new groups of invertebrate water channels based on the snail Helix pomatia L. (Helicidae) MIP protein identification and phylogenetic analysis

摘要

Water channel proteins, classified as a family of Membrane Intrinsic Proteins (MIPs) superfamily, enable rapid movement of water and small uncharged molecules through biological membranes. Although water channel proteins are required in several important processes characteristic for the animals, such as osmoregulation, mucus secretion, or defense against desiccation, molluscs, until now, have been very poorly explored in this aspect. Therefore, we decided to study MIPs in Helix pomatia L. applied as a model in studies on terrestrial snail physiology.
