摘要：

A cDNA clone isolated from an Arabidopsis thaliana cell suspension culture library showed considerable similarities to the proteasome 28 kDa a subunit of Drosophila [(1990) Gene 90, 235-241]. The 250 amino acid-long protein encoded by Arabidopsis TAS-g64 clone has important homologies in its primary structure and in the predicted secondary structure with the PROS-28.1 clone from Drosophila. The only divergence observed between the two sequences is for the 20 C-terminal amino acids. This subunit might share important functions in both kingdoms, as revealed by the important conservation between plants and animals. In plant cells it is encoded by a single-copy gene and probably regulated by stress and/or division.
