Protective roles of highly conserved motif 1 in tardigrade cytosolic-abundant heat soluble protein in extreme environments.

ABSTRACT: Tardigrades are remarkable microscopic animals that survive harsh conditions such as desiccation and extreme temperatures. Tardigrade-specific intrinsically disordered proteins (TDPs) play an essential role in the survival of tardigrades in extreme environments. Cytosolic-abundant heat soluble (CAHS) protein, a key TDP, is known to increase desiccation tolerance and to protect the activity of several enzymes under dehydrated conditions. However, the function and properties of each CAHS domain have not yet been elucidated in detail. Here, we aimed to elucidate the protective role of highly conserved motif 1 of CAHS in extreme environmental conditions. To examine CAHS domains, three protein constructs, CAHS Full (1-229), CAHS ∆Core (1-120_184-229), and CAHS Core (121-183), were engineered. T
