An investigation into the effect of ribosomal protein S15 phosphorylation on its intermolecular interactions by using phosphomimetic mutant.

An investigation using recombinant ribosomal proteins and synthetic peptide models was conducted to uncover the effect of the introduction of a negative charge at the C-terminal tail of ribosomal protein S15. Our results help provide a chemical rationale towards understanding how G2019S LRRK2, a common clinical mutation, causes Parkinson's disease.
