摘要：

ZW10 participates in the termination of the spindle checkpoint during mitosis by interacting with dynamitin, a subunit of the dynein accessory complex dynactin. We previously showed that ZW10 is attached to the endoplasmic reticulum through RINT-1 in interphase HeLa cells and involved in membrane transport between the endoplasmic reticulum and Golgi. Although a recent study demonstrated that ZW10 is localized in the Golgi in COS7 cells, the mechanism that regulates ZW10 localization remains unknown. In this study we showed a correlation between the Golgi localization of ZW10 and the centrosomal accumulation of dynactin. The amounts of ZW10 associated with dynactin were larger in cells where ZW10 was present in the Golgi than those where ZW10 was not in the Golgi. The targeting of ZW10 to the perinuclear Golgi region was found to depend on the perinuclear accumulation of dynactin, suggesting that dynactin regulates ZW10 localization. (c) 2007 Elsevier Inc.
