TatD DNase domain containing 2 pseudogene 2 (TATDN2P2)

TatD DNase domain containing 2 pseudogene 2 (TATDN2P2) is classified as a pseudogene, which means it is a duplicate or partial copy of a protein-coding gene—in this case, related to the TatD DNase domain containing 2 gene—but has been rendered nonfunctional by disabling mutations[1][2][3]. Pseudogenes do not encode functional proteins and are traditionally considered non-functional “junk” DNA; however, emerging research indicates some pseudogenes are transcribed and can regulate their parent genes through functions at the RNA level, such as acting as decoys for microRNAs or generating regulatory non-coding RNAs[1][3]. There is no evidence that TATDN2P2 is independently functional, or that it plays a direct role in disease or is a therapeutic target. Therefore, it is not considered a receptor, enzyme, transporter, or actionable drug target.
