In this case, Cdk1-dependent phosphorylation ...

WebJun 10, 2010 · Here we show that the functional human ortholog of Greatwall protein kinase (Gwl) is the microtubule-associated serine/threonine kinase-like protein, MAST-L. This kinase promotes mitotic entry and maintenance in human cells by inhibiting protein phosphatase 2A (PP2A), a phosphatase that dephosphorylates cyclin B-Cdc2 substrates. WebThe protein kinase Greatwall (Gwl) is required to maintain mitosis through PP2A inhibition. We describe how Gwl activation results in PP2A inhibition. We identified cyclic adenosine monophosphate–regulated phosphoprotein 19 (Arpp19) and a-Endosulfine as two substrates of Gwl that, when phosphorylated by this kinase, associate with
