Espn Gene Summary [Rat]
Enables SH3 domain binding activity and actin filament binding activity. Predicted to be involved in microvillar actin bundle assembly and negative regulation of cytoskeleton organization. Predicted to act upstream of or within locomotory behavior; parallel actin filament bundle assembly; and positive regulation of filopodium assembly. Located in several cellular components, including actin cytoskeleton; brush border; and microvillus. Part of filamentous actin. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 36. Orthologous to human ESPN (espin). [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 Espn often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
