Dstn Gene Summary [Rat]
Predicted to enable actin filament binding activity. Predicted to be involved in actin filament fragmentation and actin filament severing. Predicted to act upstream of or within cell motility and positive regulation of actin filament depolymerization. Predicted to be located in cortical actin cytoskeleton. Predicted to be active in several cellular components, including actin cytoskeleton; glutamatergic synapse; and postsynapse. Orthologous to human DSTN (destrin, actin depolymerizing factor).

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