Component of the large ribosomal subunit (PubMed:12962325, PubMed:23636399, PubMed:32669547). The ribosome is a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell (PubMed:12962325, PubMed:23636399, PubMed:32669547). Binds to G-rich structures in 28S rRNA and in mRNAs (PubMed:12962325). Plays a regulatory role in the translation apparatus; inhibits cell-free translation of mRNAs (PubMed:12962325). Component of the large ribosomal subunit (PubMed:12962325, PubMed:23636399, PubMed:32669547). Homodimer (PubMed:12962325). Interacts with DHX33 (PubMed:26100019). Belongs to the universal ribosomal protein uL30 family.
