MUSTN1 (Musculoskeletal, Embryonic Nuclear Protein 1) is a Protein Coding gene. It may play an important role in regulating musculoskeletal development in mammals. It belongs to the MUSTANG family. The MUSTN1 protein is localized to the nucleus in the myocardium and skeletal muscle fibers. It was expressed the greatest in skeletal muscle. The greatest relative growth rates appeared at the highest expression levels of the MUSTN1 gene, it was thought to play roles in duck muscle development. MUSTN1 is widely expressed in the prostate, fat, and other tissues. Diseases associated with MUSTN1 include Pulp Degeneration and Lacrimal System Cancer. An important paralog of this gene is ENSG00000243696.
