RPS20 (Ribosomal Protein S20): RPS20 is a ribosomal protein that plays a crucial role in ribosome assembly and protein synthesis. It is a component of the small ribosomal subunit and is essential for accurate translation. Mutations in RPS20 and other ribosomal proteins can cause ribosomopathies, a group of disorders characterized by defective ribosome function and developmental abnormalities.
