Primary Identifier | MGI:3045207 | Allele Type | Targeted |
Attribute String | Hypomorph | Gene | Spi1 |
Transmission | Germline | Strain of Origin | (129X1/SvJ x 129S1/Sv)F1-Kitl<+> |
Is Recombinase | false | Is Wild Type | false |
molecularNote | Sfpi1tm1Dgt mice were crossed with mice carrying Tg(CMV-cre)1Cgn. Activity of the cre recombinase resulted in excision of the upstream regulatory element producing a hypomorphic allele. Mice homozygous for this allele produced only about 20% of wild-type protein product. |
