Component of the large ribosomal subunit. The ribosome is a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell. Binds to G-rich structures in 28S rRNA and in mRNAs. Plays a regulatory role in the translation apparatus; inhibits cell-free translation of mRNAs. Component of the large ribosomal subunit. Homodimer. Interacts with DHX33. Belongs to the universal ribosomal protein uL30 family.
