Eps8 Gene Summary [Rat]
Predicted to enable actin binding activity and small GTPase binding activity. Predicted to be involved in several processes, including actin filament organization; barbed-end actin filament capping; and small GTPase-mediated signal transduction. Predicted to act upstream of or within several processes, including adult locomotory behavior; behavioral response to ethanol; and cellular response to leukemia inhibitory factor. Is active in glutamatergic synapse and postsynaptic density. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 102. Orthologous to human EPS8 (EGFR pathway substrate 8, signaling adaptor). [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 Eps8 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
