== Function ==
[https://www.uniprot.org/uniprot/LRRK2_HUMAN LRRK2_HUMAN] May play a role in the phosphorylation of proteins central to Parkinson disease. Phosphorylates PRDX3. May also have GTPase activity. Positively regulates autophagy through a calcium-dependent activation of the CaMKK/AMPK signaling pathway. The process involves activation of nicotinic acid adenine dinucleotide phosphate (NAADP) receptors, increase in lysosomal pH, and calcium release from lysosomes.<ref>PMID:16352719</ref> <ref>PMID:20949042</ref> <ref>PMID:21850687</ref> <ref>PMID:22012985</ref>

== Publication Abstract from PubMed ==
LRRK2 is one of the most promising drug targets for Parkinson's disease. Though type I kinase inhibitors of LRRK2 are under clinical trials, alternative strategies like type II inhibitors are being actively pursued due to the potential undesired effects of type I inhibitors. Currently, a robust method for LRRK2-inhibitor structure determination to guide structure-based drug discovery is lacking, and inhibition mechanisms of available compounds are also unclear. Here we present near-atomic-resolution structures of LRRK2 with type I (LRRK2-IN-1 and GNE-7915) and type II (rebastinib, ponatinib, and GZD-824) inhibitors, uncovering the structural basis of LRRK2 inhibition and conformational plasticity of the kinase domain with molecular dynamics (MD) simulations. Type I and II inhibitors bind to LRRK2 in active-like and inactive conformations, so LRRK2-inhibitor complexes further reveal general structural features associated with LRRK2 activation. Our study provides atomic details of LRRK2-inhibitor interactions and a framework for understanding LRRK2 activation and for rational drug design.
