LRRK2 (Q5S007) - Overview - Molecular Target Synopsis


LRRK2, Leucine-rich repeat serine/threonine-protein kinase 2
Enzyme Classification
UniProt Q5S007

Also Known as LRRK2_HUMAN, LRRK2, PARK8

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. Together with RAB29, plays a role in the retrograde trafficking pathway for recycling proteins, such as mannose 6 phosphate receptor (M6PR), between lysosomes and the Golgi apparatus in a retromer-dependent manner. Regulates neuronal process morphology in the intact central nervous system (CNS). Plays a role in synaptic vesicle trafficking. Phosphorylates PRDX3. Has GTPase activity. May play a role in the phosphorylation of proteins central to Parkinson disease. Plays an important role in recuiting SEC16A to endoplasmic reticulum exit sites (ERES) and in regulating ER to Golgi vesicle-mediated transport and ERES organization (PubMed:25201882). Homodimer. Interacts with PRKN, PRDX3, RAB29, TPCN2 and VPS35. Interacts (via ROC domain) with SEC16A (PubMed:25201882).
