Functional and behavioral consequences of Parkinson's disease-associated LRRK2-G2019S mutation.

abstract：:Post-translational modification (PTM) of histones has been investigated in eukaryotes for years, revealing its widespread occurrence and functional importance. Many PTMs affect chromatin folding and gene activity. Only recently the occurrence of such modifications has been recognized in bacteria. However, it is unclea...
