| 摘要 |
In accordance with the present invention, there are provided novel Siah-Mediated-Degradation-Proteins (SMDPs) and/or SCF-Complex Proteins (SCPs). Nucleic acid sequences encoding such proteins and assays employing same are also disclosed. The invention SMDPs and/or SCPs can be employed in a variety of ways, for example, for the production of anti-SMDP and/or SCP antibodies thereto, in therapeutic compositions, and methods employing such proteins and/or antibodies for drug screening, functional genomics and other applications. Also provided are transgenic non-human mammals that express the invention protein. Also provided are compositions and methods for targeting the destruction of selected polypeptides in eukaryotic cells based on the ubiquitin-independent mechanism by which ornithine decarboxylase is degraded by the 26S proteasome.
