In the 6 January 2015 issue of Science Signaling, Nyati et al. reported that the mitotic checkpoint kinase BUB1 promotes the activity of TGF-β receptors, which adds new molecular links between these fundamental biological processes. WebThe spindle assembly checkpoint (SAC) is critical for sensing defective microtubule–kinetochore attachments and tension across the kinetochore and functions to arrest cells in prometaphase to allow time to repair any … Web27 feb. 2024 · The authors demonstrated that rigosertib causes spindle and mitotic defects because it binds to αβ-tubulin heterodimers, in a region similar to that of to other microtubule destabilizers, such as colchicine. This binding of rigosertib to tubulin alters microtubule dynamics both in vitro and in vivo. mystic ct to albany ny
