Fscn2 Gene Summary [Mouse]
Predicted to enable actin filament binding activity. Acts upstream of or within eye photoreceptor cell development. Located in actin cytoskeleton and stereocilium. Is expressed in retina. Used to study auditory system disease; retinal degeneration; and retinitis pigmentosa 30. Human ortholog(s) of this gene implicated in retinitis pigmentosa and retinitis pigmentosa 30. Orthologous to human FSCN2 (fascin actin-bundling protein 2, retinal). [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 mouse Fscn2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- actin filament binding
- fascin-like domain, beta-trefoil fold, found in the fascin-like family
- actin binding
- protein binding
- Fascin domain
