Ribosomal protein S4X pseudogene 18 (RPS4XP18)

Ribosomal protein S4X pseudogene 18 (RPS4XP18) is classified as a processed pseudogene in the human genome. Although it shares sequence similarity with genes encoding the ribosomal protein S4 (both X- and Y-linked paralogs), which are components of the small ribosomal subunit, RPS4XP18 itself does not code for a functional protein or participate in ribosome assembly or function. It is one of numerous processed pseudogenes related to the ribosomal protein S4 gene family, typically present as non-coding genomic DNA without demonstrated biological activity or disease association. RPS4XP18 is not a protein-coding gene but a pseudogene, meaning it is a non-functional copy derived from the ribosomal protein S4 gene. It is not considered a therapeutic target, nor does it have described molecular functions in biological processes, disease associations, or pharmacological relevance. Common aliases include RPS4P18 and RPS4X_10_1587. While the protein-coding RPS4X gene is functionally important for ribosome structure and implicated in some diseases (e.g., Turner syndrome), none of these attributes apply to the RPS4XP18 pseudogene specifically. No known drugs, mechanisms of action, biomarker status, or safety concerns are described for this pseudogene.
