Anti-MSS1 antibodies enable researchers to detect and measure the MSS1 antigen in biological samples. This target is a reported synonym of the PSMC2 gene, which encodes proteasome 26S subunit, ATPase 2. This protein is known to function in osteoblast differentiation, among other biological roles. The human version of MSS1 has a canonical amino acid length of 433 residues and a protein mass of 48.6 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types. MSS1 is a member of the AAA ATPase protein family.
