Sptbn4 Gene Summary [Rat]
Predicted to enable cytoskeletal protein binding activity and phosphatase binding activity. Predicted to be involved in actin cytoskeleton organization and central nervous system projection neuron axonogenesis. Predicted to act upstream of or within several processes, including adult walking behavior; neuron development; and regulation of heart contraction. Located in axon initial segment; cytoplasm; and node of Ranvier. Orthologous to human SPTBN4 (spectrin beta, non-erythrocytic 4). [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 Sptbn4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
