A	PF21057	Hikeshi-like, C-terminal domain (Hikeshi-like_C)	Hikeshi-like, C-terminal domain	This domain is found at the C-terminal end of Protein Hikeshi from humans and its orthologues OPI10 from other eukaryotes.

This domain is found at the C-terminal end of Protein Hikeshi from humans and its orthologues OPI10 from other eukaryotes. Hikeshi is an specific nuclear import carrier for HSP70 proteins following heat-shock stress, which is required to protect cells from heat- shock damages. The intrinsically flexible C-terminal domain is responsible for the asymmetric dimeric conformation adopted by the protein, which seems to be an important regulator of Hsp70 binding. It shows three alpha-helices and a short beta-strand in a coiled-coil-like configuration [1].	Domain

This domain is found at the N-terminal end of Protein Hikeshi from humans and its orthologues OPI10 from other eukaryotes. Hikeshi is an specific nuclear import carrier for HSP70 proteins following heat-shock stress, which is required to protect cells from heat- shock damages. The N-terminal domain shows a jelly-roll/beta- sandwich fold with two layers of beta-sheets consisting of three and five and five antiparallel beta-strands [1].	Domain
