| Primary Identifier | MGI:2677883 | Allele Type | Targeted |
| Attribute String | Modified regulatory region, Null/knockout | Gene | Myl1 |
| Transmission | Germline | Strain of Origin | 129S4/SvJae |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | The MLC downstream enhancer was deleted via two steps of homologous recombination. Ultimately, the allele lacked the MLC downstream enchancer and surrounding sequence (a 1.5 kb genomic fragment) and contained no exogenous sequence. |
