Anti-dynein light chain Tctex-type 2 antibodies are used for the immunodetection of the protein encoded by the DYNLT2 gene. In humans, the canonical protein has a reported length of 198 amino acid residues and a mass of 23.2 kDa. Its subcellular localization is in the membrane and cytoplasm. It is reported to be highly expressed in the testis. A member of the Dynein light chain Tctex-type protein family, it is believed to be an accessory component of axonemal dynein and cytoplasmic dynein 1. Other names for this target antigen include TCTEX1D3, TCTEX2, Tctex4, dynein light chain Tctex-type protein 2, T-complex testis-specific protein 3, and TCTE3. Gene orthologs have been identified in the mouse, rat, bovine, chimpanzee and chicken species.
