Capzb Gene Summary [Rat]
Predicted to enable actin filament binding activity. Predicted to be involved in several processes, including barbed-end actin filament capping; regulation of cell morphogenesis; and regulation of plasma membrane bounded cell projection assembly. Predicted to act upstream of or within actin polymerization or depolymerization and lamellipodium assembly. Located in dendritic spine and neuronal cell body. Biomarker of dementia. Orthologous to human CAPZB (capping actin protein of muscle Z-line subunit beta). [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 Capzb often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
