Mattson – Protein Phosphorylation in Aging &&& Age-Related Disease

It can be argued that ATP is the most important molecule in cells. Not only is ATP the key energy source for cells, but it is also the source of phosphate groups that are transferred to a variety of substrate proteins via the action of elaborate families of protein kinases. An equally elaborate array of protein phosphatases can remove phosphate groups from proteins. It is now well established that protein phosphorylation is a widely used mechanism for cells to selectively modulate the function o
