Abstract

We isolated a rice cDNA clone encoding the ubiquitin protein fused to a ribosomal protein. This clone encodes a single ubiquitin polypeptide and extension protein of 53 amino acids. This extension protein shows a high degree of homology with those of the yeast ubil or ubi2 gene, both of which encode the same protein. Northern blot analysis suggested that the expression pattern of this gene is more similar to other ribosomal protein genes not linked to ubiquitin protein than to the polyubiquitin gene.
