Ordered dephosphorylation
WebThe AMP-dependent protein kinase (AMPK) is a master regulator of energy metabolism in most cells and is regulated allosterically by AMP binding and by phosphorylation of Thr172 in the activation loop of the AMPK alpha subunit. WebMitosis generally involves a wave of phosphorylation at entry and dephosphorylation at exit. More is understood about the role of kinases than that of phosphatases in this dynamic. Nasa et al. developed an integrated approach to study the interaction dynamics of the kinome-phosphatome in mitotic cells.
