Cby1 Gene Summary [Mouse]
Predicted to enable beta-catenin binding activity and protein homodimerization activity. Involved in cardiac muscle cell differentiation and fat cell differentiation. Acts upstream of or within cilium assembly; floor plate development; and negative regulation of canonical Wnt signaling pathway. Located in centriole and ciliary basal body. Is expressed in heart; liver; lung; and olfactory epithelium. Used to study otitis media and primary ciliary dyskinesia. Orthologous to human CBY1 (chibby 1, beta catenin antagonist).

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 Cby1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
