| Protein Name | Proteasome subunit beta type-4 | |
| Gene Name | PRE1 | |
| Organism | Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast). | |
| Sequence Length | 198 | |
| Subcellular Localization | Cytoplasm. Nucleus. | |
| Protein Description | The proteasome degrades poly-ubiquitinated proteins in the cytoplasm and in the nucleus. It is essential for the regulated turnover of proteins and for the removal of misfolded proteins. The proteasome is a multicatalytic proteinase complex that is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. It has an ATP-dependent proteolytic activity. This subunit has a chymotrypsin-like activity.. | |
