Mks1 Gene Summary [Mouse]
Involved in branching morphogenesis of an epithelial tube and cilium assembly. Acts upstream of or within several processes, including chordate embryonic development; plasma membrane bounded cell projection organization; and regulation of Wnt signaling pathway. Located in ciliary transition zone; membrane; and microtubule organizing center. Part of MKS complex. Is expressed in several structures, including brain; esophagus epithelium; lung; metanephros; and secondary heart field. Used to study Meckel syndrome; atrioventricular septal defect; and tetralogy of Fallot. Human ortholog(s) of this gene implicated in Bardet-Biedl syndrome; Bardet-Biedl syndrome 13; Joubert syndrome 28; and Meckel syndrome 1. Orthologous to human MKS1 (MKS transition zone complex subunit 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 Mks1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
