B9d1 Gene Summary [Mouse]
Enables hedgehog receptor activity. Involved in cilium assembly and smoothened signaling pathway. Acts upstream of or within several processes, including embryonic digit morphogenesis; in utero embryonic development; and neuroepithelial cell differentiation. Located in ciliary transition zone and membrane. Part of MKS complex. Is expressed in embryo and secondary heart field. Used to study Meckel syndrome. Human ortholog(s) of this gene implicated in Joubert syndrome 27 and Meckel syndrome. Orthologous to human B9D1 (B9 domain containing 1). [provided by Alliance of Genome Resources, Jul 2025]

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 B9d1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
