[[http://www.uniprot.org/uniprot/SAHS1_RAMVA SAHS1_RAMVA]] Secreted heat soluble protein acting as a molecular shield in water-deficient condition (PubMed:22937162). Tardigrade-specific intrinsically disordered proteins (TDPs) are essential for desiccation tolerance by forming non-crystalline amorphous solids upon desiccation, and this vitrified state mirrors their protective capabilities (By similarity).[UniProtKB:P0CU39]<ref>PMID:22937162</ref>

== Publication Abstract from PubMed ==
 +
Upon stopping metabolic processes, some tardigrades can undergo anhydrobiosis. Secretory abundant heat-soluble (SAHS) proteins have been reported as candidates for anhydrobiosis-related proteins in tardigrades, which seem to protect extracellular components and/or secretory organelles. We determined structures of a SAHS protein from Ramazzottius varieornatus (RvSAHS1), which is one of the toughest tardigrades. RvSAHS1 shows a beta-barrel structure similar to fatty acid-binding proteins (FABPs), in which hydrophilic residues form peculiar hydrogen bond networks, which would provide RvSAHS1 with better tolerance against dehydration. We identified two putative ligand-binding sites: one that superimposes on those of some FABPs and the other, unique to and conserved in SAHS proteins. These results indicate that SAHS proteins constitute a new FABP family.
