Web1 day ago · When P35 binds to CDK5, the enzyme’s structure changes, allowing it to phosphorylate — add a phosphate molecule to — its targets. However, in Alzheimer’s and other neurodegenerative diseases, P35 is cleaved into a smaller protein called P25, which can also bind to CDK5 but has a longer half-life than P35.
