MTX2 pseudogene 1 (MTX2P1)

MTX2 pseudogene 1 (MTX2P1), also referred to as psMTX2 or Metaxin-2 pseudogene 1, is a pseudogene of the human metaxin-2 (MTX2) gene. Pseudogenes are genomic DNA sequences similar to normal genes but are typically non-functional due to mutations such as frameshifts, premature stop codons, or missing regulatory elements. The canonical MTX2 gene encodes a mitochondrial outer membrane protein involved in protein import, mitochondrial function, and is implicated in bioenergetics and apoptosis. While parental MTX2 has biological functions and relevance in disease (for example, cancer), MTX2P1 does not encode a functional protein and is not known to have receptor, enzyme, transporter, or other therapeutic target activity[1]. Experimental evidence indicates such metaxin pseudogenes lack promoter sequences and are not expressed in tissues such as liver, confirming their non-coding status[1]. There are no drugs or therapeutic interventions known to act on MTX2P1, and it does not serve as a biomarker or have any specific safety concerns. This entry is labeled "incorrect" because MTX2P1 is not a druggable or functional target—it is a non-coding pseudogene[1]. Note: While some pseudogenes may possess regulatory (e.g., miRNA sponge) functions, there is no evidence for such a role for MTX2P1 at this time[1]. [1] provides experimental details for human MTX2/MTX2 pseudogene structure and confirms lack of expression and function for the pseudogene.
