| 摘要 |
The present invention relates to a process for producing a temperature-sensitive conditionally mutant multicellular organism using a low-temperature N-terminal degradation cassette or a vector comprising it to transfect or transform at least one cell or part of a multicellular organism, thereby obtaining the temperature-sensitive conditional mutant of the multicellular organism or part thereof. Further, the present invention relates to a low-temperature N-terminal degradation cassette comprising nucleotide sequences encoding at least a temperature-sensitive DHFR protein, a destabilizing amino acid, a ubiquitin moiety, as well as a protein of interest. |
