Adenylate kinase 4 pseudogene 2 (AK4P2)

Adenylate kinase 4 pseudogene 2 (AK4P2) is classified as a pseudogene, meaning it is a non-functional genomic sequence similar to but distinct from the functional AK4 gene. Unlike the canonical AK4 gene, which encodes a mitochondrial enzyme involved in nucleotide metabolism, AK4P2 does not encode a protein and has no known biological activity or therapeutic relevance[4][5]. Pseudogenes like AK4P2 typically arise from duplication or retrotransposition events and do not contribute to enzymatic or signaling pathways. There are no documented roles in disease, no known molecular interactions, and no evidence supporting its status as a drug target. It is maintained in the genome primarily as an evolutionary remnant[4][5]. This is not a therapeutic target (enzyme, receptor, transporter, etc.) and should not be used in contexts seeking functional or druggable targets. The query is "incorrect" in the context of therapeutic discovery, as AK4P2 is a non-coding pseudogene[4][5].
