Dynarrestin mitotic spindle
WebDec 30, 2024 · The mitotic spindle. The spindle is made of microtubules that originate from the centrosomes, which have migrated to opposite sides of the cell. There are three types of spindle microtubules: the kinetochore microtubules (K), polar microtubules (P), and astral microtubules (A). WebJul 1, 2009 · The majority of the work detailing mitotic spindle positioning has focused on activation of the Kar9p and dynein pathways. Less studied, but equally important, is the issue of how these pathways are silenced to prevent unnecessary spindle movement. In this study, we explored the mechanisms that restrict dynein-dependent spindle …
