Anti-Ktu antibodies enable researchers to detect and measure the Ktu antigen in biological samples. This target is a reported synonym of the DNAAF2 gene, which encodes dynein axonemal assembly factor 2. This protein is known to function in cellular localization and in utero embryonic development, among other biological roles. The human version of Ktu has a canonical amino acid length of 837 residues and a protein mass of 91.1 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include C14orf104 and CILD10.
