| Primary Identifier | MGI:2178119 | Allele Type | Targeted |
| Attribute String | Null/knockout | Gene | Tcf3 |
| Transmission | Germline | Strain of Origin | 129P2/OlaHsd |
| Is Recombinase | false | Is Wild Type | false |
| description | ES cell line = either E14 or E14-derived. |
| molecularNote | Insertion of a neomycin resistance cassette into the E12-specific exon disrupted the gene. RT-PCR studies of fetal liver and of lung from 5 week old mice detected trace amounts of E47-specific transcript in homozygous mutant mice. The authors predict that both gene products, E12 and E47, are inactivated in this allele. |
