Astn2 Gene Summary [Mouse]
Predicted to enable calcium ion binding activity and inositol 1,3,4,5 tetrakisphosphate binding activity. Acts upstream of or within establishment of body hair planar orientation and negative regulation of protein localization to cell surface. Located in cell pole; endosome; and membrane. Is expressed in several structures, including central nervous system; embryo mesenchyme; respiratory system; sensory organ; and skin. Orthologous to human ASTN2 (astrotactin 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 Astn2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
