Anti-NET9 antibodies enable researchers to detect and measure the NET9 antigen in biological samples. This target is a reported synonym of the TOR1AIP2 gene, which encodes torsin 1A interacting protein 2. This protein is known to be required for endoplasmic reticulum integrity. The human version of NET9 has a canonical amino acid length of 470 residues and a protein mass of 51.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus and ER of cells. NET9 is a member of the TOR1AIP protein family.
