The wheel domain is found at the C-terminus of yeast Cns1 and human TTC4 proteins [1]. The structure of the domain shows an overall fold consisting of a twisted five-stranded beta sheet surrounded by several alpha helices [1]. The Hsp90 chaperone machinery in eukaryotes comprises a number of distinct accessory factors. Cns1 is one of the few essential co-chaperones in yeast. Cns1 is important for maintaining translation elongation, specifically chaperoning the elongation factor eEF2 [1]. In this context, Cns1 interacts with the novel co-factor Hgh1 and forms a quaternary complex together with eEF2 and Hsp90 [1].
