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].

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].
