Dbn1 Gene Summary [Rat]
Enables actin filament binding activity; cytoskeletal motor inhibitor activity; and profilin binding activity. Involved in several processes, including regulation of nervous system process; regulation of organelle organization; and regulation of plasma membrane bounded cell projection organization. Located in several cellular components, including actin filament; axon; and dendrite. Is active in glutamatergic synapse; postsynaptic actin cytoskeleton; and postsynaptic membrane. Biomarker of Parkinson's disease; cognitive disorder; sciatic neuropathy; temporal lobe epilepsy; and transient cerebral ischemia. Orthologous to human DBN1 (drebrin 1).

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 Dbn1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
