Anti-NS2 antibodies enable researchers to detect and measure the NS2 antigen in biological samples. This target is a reported synonym of the LZTR1 gene, which encodes leucine zipper like post translational regulator 1. This protein is known to function in protein ubiquitination, among other biological roles. The human version of NS2 has a canonical amino acid length of 840 residues and a protein mass of 94.7 kilodaltons. It is reported to be localized in the Golgi of cells and notably expressed in many tissues, such as the breast, stomach, and appendix. NS2 is a member of the LZTR1 protein family.
