Anti-t-complex-associated testis expressed 3 antibodies are used in antigen-specific immunodetection in biological samples. The target t-complex-associated testis expressed 3 is a known alias name of the protein dynein light chain Tctex-type 2, encoded by the DYNLT2 gene in humans. This 198-amino acid residue protein is believed to be an accessory component of axonemal dynein and cytoplasmic dynein 1. It is localized to the membrane and cytoplasm of the cell. In terms of tissue expression, it is reported to be highly expressed in the testis. Other synonyms for t-complex-associated testis expressed 3 include TCTE3, TCTE3, and TCTEX1D3.
