SBDS proteins are essential for the assembly of mature ribosomes and ribosome biogenesis. It cooperates with EFL1 to catalyze the GTP-dependent release of EIF6 from 60S preribosomes in the cytoplasm, activating the translation ability of ribosomes. SBDS Protein, Mouse (His) is the recombinant mouse-derived SBDS protein, expressed by E. coli , with N-His labeled tag.
