Supplementary information

The protein LRRK2 also known as leucine-rich repeat kinase 2 or dardarin is an enzyme with a molecular weight of approximately 286 kDa. It functions as a kinase meaning it adds phosphate groups to other proteins which affects their activity. LRRK2 is expressed in various tissues but it is highly abundant in the brain especially in regions such as the striatum and cortex. It has a significant role in cellular signaling processes due to its phosphorylation activity.
Biological function summary

LRRK2 interacts with cellular mechanisms by regulating cytoskeletal dynamics autophagy and vesicle trafficking. It is a part of a larger complex that includes other proteins involved in these processes. The kinase activity of LRRK2 plays an essential part in maintaining neuronal health and function. It influences the process of autophagy which is a way cells clean themselves by removing damaged components and recycling them.

Pathways

The action of LRRK2 is central to the mitogen-activated protein kinase (MAPK) and the mammalian target of rapamycin (mTOR) pathways. In these pathways LRRK2 interacts with other proteins such as mTOR and RPS6KB1. It modulates cellular processes like growth proliferation and response to stressors. Its kinase activity affects the phosphorylation state of targets within the pathways hence influencing biological outcomes like survival and apoptosis.

LRRK2 mutations have a significant connection to Parkinson's disease and Crohn's disease. In Parkinson's disease mutated LRRK2 leads to abnormal protein aggregation linking to proteins such as alpha-synuclein. For Crohn's disease LRRK2 influences the immune response and intestinal inflammation. These connections highlight LRRK2's role in the pathogenesis and contribute to understanding these complex disorders.

General info

Function

The protein expressed by the gene LRRK2 is a serine/threonine-protein kinase that phosphorylates a wide range of proteins involved in neuronal plasticity, autophagy, and vesicle trafficking. It serves as a key regulator of RAB GTPases by affecting the GTP/GDP exchange and interaction partners of RABs through phosphorylation, targeting proteins like RAB3A, RAB3B, and others. LRRK2 manages the GDP/GTP exchange for RAB8A by phosphorylating 'Thr-72', inhibiting RAB8A's interaction with GDI1/GDI2, and influencing primary ciliogenesis to enhance SHH signaling in the brain. It works with RAB29 in retromer-dependent recycling of proteins between lysosomes and the Golgi. The protein is involved in shaping neuronal morphology in the CNS, synaptic vesicle trafficking, and recruiting SEC16A to assist in ER to Golgi transport. It enhances autophagy via the CaMKK/AMPK pathway and relates to nicotinic acid adenine dinucleotide phosphate receptors and lysosomal activity. LRRK2 phosphorylates PRDX3 and APP, influencing neuron apoptosis. Independently, it inhibits MAPT degradation, fostering MAPT oligomerization. Additionally, LRRK2 possesses GTPase activity that regulates its kinase activity. This supplementary information is collated from multiple sources and compiled automatically.

Sequence similarities

Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family.

Post-translational modifications

Autophosphorylated at Ser-1292; autophosphorylation is stimulated by RAB29 (PubMed:28202711, PubMed:28720718, PubMed:29127255, PubMed:29212815, PubMed:30635421, PubMed:38127736). Phosphorylation of Ser-910 and either Ser-935 or Ser-1444 facilitates interaction with YWHAG (PubMed:28202711). Phosphorylation of Ser-910 and/or Ser-935 facilitates interaction with SFN (PubMed:28202711).. Ubiquitinated by TRIM1; undergoes 'Lys-48'-linked polyubiquitination leading to proteasomal degradation.
