Dkk2 Gene Summary [Mouse]
Enables co-receptor binding activity. Involved in negative regulation of Wnt signaling pathway. Predicted to be located in extracellular region. Predicted to be active in extracellular space. Is expressed in several structures, including central nervous system; embryo mesenchyme; eye; genitourinary system; and jaw. Orthologous to human DKK2 (dickkopf WNT signaling pathway inhibitor 2).

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 Dkk2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
