5S ribosomal RNA 7 (5S rRNA 7)

5S ribosomal RNA (5S rRNA) is a short (about 120-nucleotide) non-coding RNA that is a structural and functional component of the large subunit of cytoplasmic ribosomes in all domains of life except fungal and animal mitochondria[1][2]. It is involved in ribosome assembly and the process of translation, helping coordinate the functional centers of the ribosome, maintain its structure, and ensure translational fidelity[1][3]. Eukaryotic genomes contain multiple 5S rRNA gene copies arranged in tandem, and individual copies (such as "5S ribosomal RNA 7") are not considered functionally distinct or individual targets[2]. 5S rRNA does not function as a receptor, enzyme, or other classic drug target, and it is essential for ribosomal structural integrity and therefore cell viability[1][2][3]. There are no drugs that act specifically on 5S rRNA nor are there therapeutic or biomarker applications for individual 5S rRNA gene variants. Key references for this information are the literature syntheses on 5S rRNA structure and its role in the ribosome[1][2][3]. "RNA5S7" or "5S ribosomal RNA 7" most likely refers to a single copy among the multiple 5S rRNA gene copies, and this is of structural, not therapeutic, interest. The nomenclature in the query does not reflect a recognized therapeutic target or a widely used gene symbol.

None specific. Antibiotics act on the ribosome as a complex, not directly via 5S rRNA[3].
