| Primary Identifier | MGI:1857717 | Allele Type | Targeted |
| Attribute String | Null/knockout, Reporter | Gene | Flt1 |
| Transmission | Germline | Strain of Origin | (129X1/SvJ x 129S1/Sv)F1-Kitl<+> |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | A LacZ-neomycin resistance cassette replaced sequences that encode the signal peptide. The authors predict this is a null allele because the translation start site is removed and reinitiation at the first two downstream Kozak sequences would result in out-of-frame translated products. |
