| Primary Identifier | MGI:5634958 | Allele Type | Targeted |
| Attribute String | Modified isoform(s) | Gene | Fosb |
| Transmission | Germline | Strain of Origin | 129S/SvEv-Gpi1<c> |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | Three bases (GAGGTGAGA->GAAGTTCGA) in the alternative splicing donor site and two bases (AGTGAA->TCTGAA) in the splice acceptor site were modified via homologous recombination to prevent expression of the long transcript while retaining expression of the shorter transcript. A floxed neo cassette was also inserted in intron 3. Cre mediated recombination removed the neo cassette. This allele lacks expression of the deltaFosb isoform. |
