Il1r1 Gene Summary [Rat]
Enables ionotropic glutamate receptor binding activity. Involved in several processes, including interleukin-1-mediated signaling pathway; positive regulation of neuron migration; and response to odorant. Located in axon; cell surface; and extracellular space. Part of protein-containing complex. Biomarker of pulpitis. Human ortholog(s) of this gene implicated in chronic recurrent multifocal osteomyelitis; systemic scleroderma; and type 1 diabetes mellitus. Orthologous to human IL1R1 (interleukin 1 receptor type 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 rat Il1r1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
