Ribosomal protein L12 pseudogene 9 (RPL12P9)

Ribosomal protein L12 pseudogene 9 (RPL12P9) is annotated as a processed pseudogene related to the ribosomal protein L12 family[6]. Pseudogenes are segments of DNA, often remnants of once-functional genes that have lost their protein-coding ability or are otherwise no longer expressed in the cell[1][6]. RPL12P9 shares sequence homology with the functional ribosomal protein L12 gene (RPL12), which codes for a component of the 60S ribosomal subunit involved in protein synthesis[1][3]. However, RPL12P9 itself does not encode a functional protein and is not known to have a role in cellular processes, disease association, or therapeutic targeting[6]. RPL12P9 is distinct from the functional RPL12 gene, which encodes the ribosomal protein L12 involved in ribosome assembly and protein synthesis[1][3]. As a pseudogene, RPL12P9 may exist as non-coding DNA or a non-functional transcript and lacks demonstrated biological or clinical utility[6]. It is not referenced as a target for any drug, nor as a marker for disease or patient selection[6].
