Anti-KTZS antibodies enable researchers to detect and measure the KTZS antigen in biological samples. This target is a reported synonym of the ROGDI gene, which encodes rogdi atypical leucine zipper. This protein is known to function in brain development and the regulation of cell proliferation, among other biological roles. The human version of KTZS has a canonical amino acid length of 287 residues and a protein mass of 32.3 kilodaltons. It is reported to be localized in the nucleus and cytoplasmic vesicles of cells. KTZS is a member of the Rogdi protein family.
