Protection and deprotection of the Rec8 cohesin complex during meiosis
{{output}}
During meiosis I, the cohesin Rec8 is cleaved by separase along the chromosome arms but is protected at the centromere by shugoshin (Sgo1); during meiosis II, it is not protected. In fission yeast, another meiotic regulator, meikin (Moa1), supports the protect... ...
