| Primary Identifier | MGI:2663639 | Allele Type | Targeted |
| Attribute String | Null/knockout, Reporter | Gene | Maff |
| Transmission | Germline | Strain of Origin | (129X1/SvJ x 129S1/Sv)F1-Kitl<+> |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | As in Mafftm1Jeng, the entire coding region, except for the first 3 codons, was replaced with a cassette containing lacZ and a floxed selection region. Prior to implantation and germline transmission, the floxed region was excised via cre mediated recombination, leaving lacZ intact. |
