Actr2 Gene Summary [Mouse]
Predicted to enable cytoskeletal protein binding activity. Predicted to be a structural constituent of cytoskeleton. Predicted to contribute to actin filament binding activity. Acts upstream of or within several processes, including cellular response to type II interferon; meiotic chromosome movement towards spindle pole; and meiotic cytokinesis. Located in actin cap. Is expressed in cochlea and metanephros. Orthologous to human ACTR2 (actin related protein 2). [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 Actr2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
