Macro domain containing 2 pseudogene

Macro domain containing 2 pseudogene (ENSG00000271608) is annotated as a processed pseudogene—an inactive genomic DNA segment derived from a previously functional gene encoding a macrodomain-containing protein. Pseudogenes arise from gene duplication or retrotransposition events, accumulating mutations that prevent their transcription or translation into functional protein products[2][5]. The macro domain is a ~130–190 amino acid module found in various proteins with roles in ADP-ribose binding, DNA repair, chromatin regulation, and post-translational modification[1][3][4], but in this case, the pseudogene does not encode functional protein. Although pseudogenes may occasionally regulate other genes as competing endogenous RNAs (ceRNAs) or affect microRNA networks[7], there is no evidence that Macro domain containing 2 pseudogene plays an active biological role or represents a therapeutic target. Such entities are generally excluded from drug development pipelines and clinical biomarker lists unless new functionality is experimentally demonstrated.
