Phosphorylation activates or inactivates
In biochemistry, phosphorylation is the attachment of a phosphate group to a molecule or an ion. This process and its inverse, dephosphorylation, are common in biology and could be driven by natural selection. Protein phosphorylation often activates (or deactivates) many enzymes. WebOct 17, 2000 · The present study identifies a mode of GSK-3 phosphorylation and inactivation independent of a functional PI3K–PKB pathway. We demonstrate that serine 21 in GSK-3α and serine 9 in GSK-3β are also physiological substrates of cAMP-dependent protein kinase A (PKA). PKA physically associates with, phosphorylates, and inactivates …
