The CS and CHORD (Pfam:PF04968) are fused into a single polypeptide chain in metazoans but are found in separate proteins in plants; this is thought to be indicative of an interaction between CS and CHORD [1]. It has been suggested that the CS domain is a binding module for HSP90, implying that CS domain-containing proteins are involved in recruiting heat shock proteins to multiprotein assemblies [2]. Two CS domains are found at the N-terminus of Ubiquitin carboxyl-terminal hydrolase 19 (USP19) (Swiss:O94966), these domains may play a role in the interaction of USP19 with cellular inhibitor of apoptosis 2 [3].
