Anti-Torsin 4A antibodies enable researchers to detect and measure the Torsin 4A antigen in biological samples. This target is a reported synonym of the TOR4A gene, which encodes torsin family 4 member A. The human version of Torsin 4A has a canonical amino acid length of 423 residues and a protein mass of 46.9 kilodaltons. It is reported to be localized in the membrane of cells and widely expressed in many tissue types. Torsin 4A is a member of the ClpA/ClpB protein family.
