RPL44 AND RPL44', ENCODING ACIDIC RIBOSOMAL PHOSPHOPROTEINS YP2-ALPHA(L44) AND YP1-BETA(L44'), ARE ADJACENT TO RIG AND STF1 ON SACCHAROMYCES-CEREVISIAE CHROMOSOMES XV AND IV RESPECTIVELY

The RPL44' gene from Saccharomyces cerevisiae encoding the ribosomal p rotein YP1 beta(L44') has been found to be linked to the STF1 gene, en coding a stabilizing factor of the F1F0-ATPase inhibitor protein from mitochondria. Evidence of this linkage comes from results obtained fro m Northern hybridization using a DNA probe that contains a complementa ry region to the 5' end of the mRNA of RPL44'. Similarly, a data bank search has shown that RPL44, encoding ribosomal protein YP2 alpha(L44) is linked to the rig gene that encodes ribosomal protein S21.
