Grn Gene Summary [Rat]
Predicted to enable protein-folding chaperone binding activity. Involved in several processes, including chondrocyte proliferation; positive regulation of dendritic spine development; and response to estradiol. Is active in glutamatergic synapse. Biomarker of status epilepticus. Human ortholog(s) of this gene implicated in dementia (multiple); neurodegenerative disease (multiple); neuronal ceroid lipofuscinosis 11; and primary progressive multiple sclerosis. Orthologous to human GRN (granulin precursor). [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 rat Grn often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
