Nphp4 Gene Summary [Rat]
Predicted to be involved in negative regulation of canonical Wnt signaling pathway; positive regulation of bicellular tight junction assembly; and protein localization to ciliary transition zone. Predicted to act upstream of or within several processes, including flagellated sperm motility; photoreceptor cell maintenance; and photoreceptor cell outer segment organization. Located in ciliary basal body. Human ortholog(s) of this gene implicated in Joubert syndrome 4; Senior-Loken syndrome; congenital heart disease; nephronophthisis; and nephronophthisis 4. Orthologous to human NPHP4 (nephrocystin 4). [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 rat Nphp4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
