Involved in the biogenesis of the 60S ribosomal subunit. May act as a specificity factor that binds precursor rRNAs and tethers the enzymes that carry out the early 5' to 3' exonucleolytic reactions that generate the mature rRNAs. Present with 7720 molecules/cell in log phase SD medium. Belongs to the universal ribosomal protein uL30 family.
