Putative oxidoreductase that negatively regulates the retrieval of cargo from late endosomes to the Golgi. Regulates YIF1 and KEX2 localization. Required for fast DNA replication. Interacts with BTN2. The recruitment from the cytoplasm to endosomal structures is facilitated by BTN2. Leads to cell death when overexpressing the camptothecin mimetic TOP1-T(722)A mutant. Present with 5240 molecules/cell in log phase SD medium. Belongs to the TDA3 family. Truncated N-terminus.
