Abstract
Ubiquitin is an abundantly expressed protein in all eukaryotic organisms. A gene for plant ubiquitin, isolated from Arabidopsis thaliana, has been used in a plant expression vector to produce a ubiquitin-protein fusion. Natural factors in the plant cleave such a fusion protein to release ubiquitin and the desired protein. It has been found that such fusions result in protein expression levels higher than those that can be obtained from expression of the protein alone.
