摘要
Human Hikeshi (HsHikeshi) is a nuclear import carrier for Hsp70s and is required for cell survival after heat shock. The Hikeshi homolog in Schizosaccharomyces pombe (SpHikeshi/Opi10) localizes to the nuclear rim, interacts with the Hsp70 homolog Ssa2, and mediates its nuclear import in a reconstituted mammalian nuclear transport system. However, SpHikeshi/Opi10 is not required for heat stress response and survival after heat stress. Instead, SpHikeshi/Opi10 is required for the normal expression of stress response genes under optimal conditions and for cell growth during glucose deprivation. Here, the functions of SpHikeshi/Opi10 are discussed and compared to the functions of HsHikeshi.
