Shugoshin N-terminal coiled-coil region The Shugoshin protein is found to have this conserved N-terminal coiled-coil region and a highly conserved C-terminal basic region, family Shugoshin_C pfam07557. Shugoshin is a crucial target of Bub1 kinase function at kinetochores, necessary for both meiotic and mitotic localization of shugoshin to the kinetochore. Human shugoshin is diffusible and mediates kinetochore-driven formation of kinetochore-microtubules during bipolar spindle assembly. Further, the primary role of shugoshin is to ensure bipolar attachment of kinetochores, and its role in protecting cohesion has co-developed to facilitate this process. |
