Anti-OTOSP antibodies enable researchers to detect and measure the OTOSP antigen in biological samples. This target is a reported synonym of the OTOS gene, which encodes otospiralin. This protein is believed to be essential for the survival of the neurosensory epithelium of the inner ear. The human version of OTOSP has a canonical amino acid length of 89 residues and a protein mass of 9.9 kilodaltons. It is reported to be a secreted protein. OTOSP is a member of the Otospiralin protein family.
