MIX23 pseudogene 1 (MIX23P1)

MIX23 pseudogene 1 (MIX23P1) is a pseudogene, meaning it is a non-functional DNA sequence similar to a functional gene (in this case, related to MIX23/Mitochondrial Matrix Import Factor 23), but does not produce a functional protein[5]. Pseudogenes are often considered genomic "fossils"; they can arise through gene duplication or retrotransposition and typically contain disabling mutations preventing functional protein expression[2][3][4][6]. While some pseudogenes have regulatory roles affecting the post-transcriptional regulation of protein-coding genes, there is no evidence that MIX23P1 itself is a validated or functionally characterized gene, nor is it a receptor, enzyme, transporter, or therapeutic target[5]. Key notes: - MIX23P1 is not a recognized drug or therapeutic target and has no known function, disease roles, or drug interactions in current biomedical literature[5][7]. - The functional gene MIX23 (also called CCDC58, “Mitochondrial Matrix Import Factor 23”) is distinct from its pseudogene; only MIX23 encodes a mitochondrial import protein[1][7]. - MIX23P1 should not be listed as a target in drug discovery or functional genomics contexts, and its inclusion is likely due to a misannotation or irrelevancy for therapeutic purposes[5][7].
