SAHS/CAHS expression (IMAGE) National Institutes of Natural Sciences Caption The tardigrade-specific genes SAHS and CAHS are thought to be involved in anhydrobiosis. TardiVec showed that the SAHS gene is mainly expressed in storage cells floating in the body cavity, and then the SAHS protein is secreted extracellularly and spreads throughout the body. The CAHS gene was mainly expressed in cells in the epidermis, and the CAHS protein is localized in the cytoplasm.
