Mns1 Gene Summary [Rat]
Predicted to enable identical protein binding activity. Predicted to be involved in positive regulation of cilium assembly and sperm axoneme assembly. Predicted to act upstream of or within left/right axis specification. Predicted to be located in cytoskeleton; cytosol; and nucleus. Predicted to be active in axonemal A tubule inner sheath and sperm flagellum. 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 rat 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.
- Trichohyalin-plectin-homology domain
- protein binding
- identical protein binding
