This transition — from a sprawled stance (like a lizard) to an upright (parasagittal) posture — marked a pivotal moment in mammal evolution. While the earliest […] Written by Admin June 30, 2025June 30, 2025 Saving Bookmark this article Bookmarked Biology A coordinated kinase and phosphatase network regulates Stu2 recruitment to yeast kinetochores Cells coordinate diverse events at anaphase onset, including separase activation, cohesin cleavage, chromosome separation, and spindle reorganization. Regulation of the XMAP215 family member and microtubule polymerase, Stu2, at the metaphase-anaphase transition determines a redistribution from kinetochores to spindle microtubules. We show that cells modulate Stu2 kinetochore-microtubule localization by Polo-like kinase1/Cdc5-mediated phosphorylation of T866, near the […] Written by Admin June 29, 2025June 29, 2025 Saving Bookmark this article Bookmarked Pharmaceuticals and Drug Development Access Denied Access Denied You don’t have permission to access ” on this server.
