To help determine the role of Sen1 in vivo, we attempted to overexpress the protein in yeast cells. However, cells with a high-copy SEN1-bearing plasmid, although expressing elevated amounts of SEN1 mRNA, show little increase in the level of the encoded protein, indicating that a posttranscriptional mechanism limits SEN1 expression. This control depends on an amino-terminal element of Sen1. Using a genetic selection for mutants with increased expression of Sen1-derived fusion proteins, we identified mutations in a novel gene, designated SEN3. SEN3 is essential and encodes a 945-residue protein with sequence similarity to a subunit of an activator of the 20S proteasome from bovine erythrocytes, called PA700. Earlier work indicated that the 20S proteasome associates with a multisubunit regulatory factor, resulting in a 26S proteasome complex that degrades substrates of the ubiquitin system. Mutant sen3-1 cells have severe defects in the degradation of such substrates and accumulate ubiquitin-protein conjugates. Most importantly, we show biochemically that Sen3 is a subunit of the 26S proteasome. These data provide evidence for the involvement of the 26S proteasome in the degradation of ubiquitinated proteins in vivo and for a close relationship between PA700 and the regulatory complexes within the 26S proteasome, and they directly demonstrate that Sen3 is a component of the yeast 26S proteasome."xsd:string |
