The C-terminal domain of Pih1 consists of a seven-stranded beta sandwich with the topology of a CS domain, a structural motif also f ...	The Pih1 protein is part of the R2TP complex [1]. The CS domain of Pih1 binds to the unstructured region of Tah1 [1]. The C-terminal domain of Pih1 consists of a seven-stranded beta sandwich with the topology of a CS domain, a structural motif also found in Hsp90 cochaperones such as p23/Sba1 and Sgt1.	Domain
