Mns1 Gene Summary [Mouse]
Predicted to enable identical protein binding activity. Involved in positive regulation of cilium assembly and sperm axoneme assembly. Acts upstream of or within cilium organization and left/right axis specification. Located in axoneme; intermediate filament; and nuclear envelope. Is active in axonemal A tubule inner sheath and sperm flagellum. Is expressed in several structures, including brain; genitourinary system; gut; hemolymphoid system gland; and liver and biliary system. Human ortholog(s) of this gene implicated in visceral heterotaxy 9. Orthologous to human MNS1 (meiosis specific nuclear structural 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 Mns1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
