Lrrk2 Gene Summary [Rat]
Predicted to enable several functions, including GTP binding activity; cytoskeletal protein binding activity; and protein serine/threonine kinase activity. Involved in several processes, including cellular response to curcumin; nervous system development; and positive regulation of microglial cell activation. Located in axon; dendrite; and perikaryon. Is active in presynaptic cytosol. Used to study neurodegenerative disease and synucleinopathy. Biomarker of diabetic neuropathy. Human ortholog(s) of this gene implicated in Crohn's disease; Parkinson's disease; Parkinson's disease 8; Parkinsonism; and cancer. Orthologous to human LRRK2 (leucine rich repeat kinase 2).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Lrrk2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
