Structures of Parkinson’s disease-linked proteins offer a framework for understanding how they work together

Scientists at St. Jude Children’s Research Hospital have revealed the complex structure of two Parkinson’s disease-related proteins, both of which are implicated in late-onset cases. Leucine-rich repeat kinase 2 (LRRK2) is a protein kinase that modifies other proteins in a process called phosphorylation; Rab29, a member of the Rab GTPase family that regulates cellular trafficking, modulates the activity of LRRK2.
