Lrrk1 Gene Summary [Mouse]
Predicted to enable identical protein binding activity and protein kinase activity. Acts upstream of or within several processes, including bone resorption; osteoclast development; and regulation of peptidyl-tyrosine phosphorylation. Predicted to be located in cytosol and mitochondrion. Predicted to be active in cytoplasm. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; hemolymphoid system; and sensory organ. Used to study osteopetrosis. Human ortholog(s) of this gene implicated in osteosclerotic metaphyseal dysplasia. Orthologous to human LRRK1 (leucine rich repeat kinase 1). [provided by Alliance of Genome Resources, Jul 2025]

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 mouse Lrrk1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
