429-Securin-Independent Regulation of Separase by SGO2

This research identifies shugoshin 2 (SGO2) as a critical, direct inhibitor of separase in human cells, functioning through a previously unknown pathway controlled by the spindle assembly checkpoint (SAC). While the protein securin was long considered the primary regulator of chromosome segregation, these findings reveal that SGO2 can functionally replace it by binding to MAD2 to block the active ...去小宇宙查看完整单集简介
