Iqcb1 Gene Summary [Mouse]
Predicted to enable several functions, including BBSome binding activity; calmodulin binding activity; and enzyme binding activity. Involved in cilium assembly. Located in photoreceptor connecting cilium and photoreceptor outer segment. Is expressed in several structures, including heart ventricle; metanephros; retina; and telencephalon ventricular layer. Human ortholog(s) of this gene implicated in Leber congenital amaurosis; Senior-Loken syndrome; nephronophthisis; and retinitis pigmentosa 3. Orthologous to human IQCB1 (IQ motif containing B1).

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 Iqcb1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
