Ribosomal protein

Ribosomal protein translation refers to the fundamental cellular process in which the genetic information encoded in messenger RNA (mRNA) is decoded by the ribosome—a large ribonucleoprotein complex composed of ribosomal RNA and ribosomal proteins—to synthesize specific proteins. Proper function of ribosomal proteins ensures accurate translation initiation, elongation, and termination, and is tightly regulated in response to developmental, metabolic, and stress signals. Dysregulation of ribosomal protein translation is implicated in diverse human diseases, including cancer, neurodegenerative disorders, and ribosomopathies such as Diamond-Blackfan anemia. Numerous drugs target this process, especially as antibiotics or in cancer therapeutics, by inhibiting key steps in translation or specific ribosomal subunits. The process itself is not a single molecule but a coordinated function involving the ribosome, mRNA, tRNAs, and translation factors[1][2][3][4][5].
