Abi3 Gene Summary [Mouse]
Predicted to enable actin filament binding activity; identical protein binding activity; and signaling adaptor activity. Involved in defense response to tumor cell; negative regulation of lamellipodium assembly; and negative regulation of protein localization to plasma membrane. Located in lamellipodium. Part of SCAR complex. Is expressed in several structures, including genitourinary system; gut; heart ventricle; lung; and spleen. Orthologous to human ABI3 (ABI family member 3).

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 Abi3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
