This chemical similarity can be exploited in cancer, where a protein may mutate into an "always on" (constitutively active) state. A mutation may occur to replace a tyrosine (which needs to be phosphorylated in order to activate the protein) with an aspartic acid (which would not need to be phosphorylated). In a laboratory setting, the use of recombinant proteins to artificially introduce phosphomimetics is a common tool for studying phosphorylation and protein activation. For exa… WebApr 12, 2024 · In addition, glutamic acid negative charge does not seem to be able to mimic the phosphorylation state of serine 112.

WebMar 28, 1997 · Microtubule-associated protein tau is a neuronal phosphoprotein that promotes microtubule assembly in vitro and has been shown to play a role in the development of axonal morphology. Tau can be phosphorylated in vitro by several kinases, some of which cause a change in the conformation and activities of tau.
