Ttc8 Gene Summary [Mouse]
Predicted to enable RNA polymerase II-specific DNA-binding transcription factor binding activity. Involved in cilium assembly and fat cell differentiation. Acts upstream of or within several processes, including morphogenesis of a polarized epithelium; negative regulation of GTPase activity; and nervous system development. Located in membrane and photoreceptor connecting cilium. Part of BBSome. Is expressed in sensory organ; spermatid; and telencephalon. Used to study Bardet-Biedl syndrome 8. Human ortholog(s) of this gene implicated in Bardet-Biedl syndrome; Bardet-Biedl syndrome 8; and retinitis pigmentosa 51. Orthologous to human TTC8 (tetratricopeptide repeat domain 8).

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 Ttc8 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
