Heterologous complementation reveals that mutant alleles of QSR1 render 60S ribosomal subunits unstable and translationally inactive.

Abstract excerpt

QSR1 is a highly conserved gene which encodes a 60S ribosomal subunit protein that is required for joining of large and small ribosomal subunits. In this report we demonstrate heterologous complementation of a yeast QSR1 deletion strain with both the human and corn homologs and show that the human and corn proteins are assembled into hybrid yeast/human and yeast/corn ribosomes. While the homologous genes...
