Cytochrome c oxidase subunit 4I1 pseudogene 1 (COX4I1P1)

Cytochrome c oxidase subunit 4I1 pseudogene 1 (COX4I1P1) is a processed pseudogene in the human genome, meaning it is a non-functional copy of the gene encoding cytochrome c oxidase subunit 4 isoform 1[4][5]. Pseudogenes like COX4I1P1 arise through gene duplication or retrotransposition and usually lack the regulatory elements or intact coding sequences required for protein production[1][5]. While many pseudogenes have traditionally been considered "junk DNA," emerging evidence suggests some may play regulatory roles at the RNA level, such as modulation of gene expression through RNA interference, antisense activity, or acting as microRNA decoys. However, there is no evidence that COX4I1P1 itself exerts such functions; its biological significance, if any, is unknown[1][4][5].
