Sac activation
WebDec 9, 2013 · Improper kinetochore attachments activate the spindle assembly checkpoint (SAC) to prevent anaphase onset, but it is poorly understood how this checkpoint is silenced to allow anaphase onset. Chromosome bipolar attachment applies tension on sister kinetochores, and the lack of tension delays anaphase onset. WebJun 7, 2011 · Although several centromeric and kinetochore kinases, including Aurora B, regulate kinetochore-microtubule attachment and/or SAC activation [2-4], the molecular mechanism that translates bioriented attachment into SAC silencing remains unclear [5].

WebJun 27, 2024 · SAC detects unattached microtubules or tension and causes metaphase arrest to ensure that all chromosomes are attached and aligned properly. Defects in the SAC result in aneuploidy and subsequently, cell death or the formation of cancerous cells (Bharadwaj and Yu 2004; Sun and Kim 2012 ). WebMar 17, 2014 · Activation of anaphase-promoting complex/cyclosome (APC/C (Cdc20)) by Cdc20 is delayed by the spindle assembly checkpoint (SAC). When all kinetochores come under tension, the SAC is turned off and APC/C (Cdc20) degrades cyclin B and securin, which activates separase [1]. The latter then cleaves cohesin holding sister chromatids …
