The transport of water and small uncharged molecules across prokaryotic and eukaryotic cell membranes is supported by aquaporins. In spite of their importance, molluscan aquaporins have not been thoroughly explored. This is worth addressing since data concerning water channels in molluscs generally shed new light on aquaporins. Our analysis of these proteins revealed a novel composition of amino acids in the ar/R region, a unique group of aquaporins in phylogenetic relationships, and the impact of environmental conditions on water channels. Additionally, we present new research about changes in the expression level of Helix pomatia aquaporins during entry into the state of aestivation. Transcriptome expression patterns obtained for feet, kidneys, and intestines from active snails housed for 3, 7, 15, and 35 days without food or water confirm the importance of aquaporins in counteracting water stress.

水通道蛋白支持水和不带电的小分子跨原核和真核细胞膜的运输。尽管它们很重要，但尚未对软体动物水通道蛋白进行深入研究。这是值得解决的，因为有关软体动物中水通道的数据通常为水通道蛋白提供了新的思路。我们对这些蛋白质的分析揭示了ar / R区中氨基酸的新颖组成，系统发育关系中独特的水通道蛋白类以及环境条件对水通道的影响。此外，我们提出了有关螺旋藻表达水平变化的新研究。水通道蛋白在进入培养状态时。从没有食物或水的情况下饲养3、7、15和35天的活动蜗牛获得的脚，肾和肠的转录组表达模式证实了水通道蛋白在抵抗水分胁迫中的重要性。
