Anti-AMSH antibodies enable researchers to detect and measure the AMSH antigen in biological samples. This target is a reported synonym of the STAMBP gene, which encodes STAM binding protein. This protein is known to function in cell division and the regulation of cell proliferation, among other biological roles. The human version of AMSH has a canonical amino acid length of 424 residues and a protein mass of 48.1 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the membrane, nucleus, and cytoplasm of cells. AMSH is a member of the Peptidase M67C protein family.
