Anti-Musclin antibodies enable researchers to detect and measure the Musclin antigen in biological samples. This target is a reported synonym of the OSTN gene, which encodes osteocrin. This protein is known to function in cell differentiation and receptor-mediated signaling pathways, among other biological roles. The human version of Musclin has a canonical amino acid length of 133 residues and a protein mass of 14.7 kilodaltons. It is reported to be a secreted protein. Musclin is a member of the Osteocrin protein family.
