✦ Synopsis

We have measured the synthesis and stability of ribosomal proteins in a temperature sensitive strain of yeast which at the restrictive temperature is specifically blocked in the processing of 27S ribosomal precursor RNA. We find that in the absence of 60S ribosomal subunit assembly, the synthesis of all the ribosomal proteins studied continued. However, the proteins of the 60S subunit fail to accumulate and are rapidly degraded.

QM is a human cDNA originally isolated as a transcript elevated in a nontumorigenic Wilms' tumor microcell hybrid, relative to the tumorigenic parental cell line. The QM gene encodes a 24 kDa basic protein that peripherally associates with the ribosomes. Recently, the gene for this protein has also

In the above paper (Yeast 11: 761-766 (1995)) ribosomal protein L17a is erroneously referred to as L17, which is a ribosomal protein distinct from L17a. All references to the products of the RPL 17A and RPL 17B genes should be L 17a.
