| Primary Identifier | MGI:4949259 | Allele Type | Targeted |
| Attribute String | Null/knockout | Gene | Mir9-3 |
| Transmission | Germline | Strain of Origin | (C57BL/6NCrlj x CBA/JNCrlj)F1 |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | A 90 nt region encoding the mature microRNA was replaced with a floxed pgk-neo cassette via homologous recombination. Quantitative RT-PCR analysis confirmed the absence of RNA expression and lack of any compensatory increase in Mir9-1 expression in homozygous mice null for both Mir9-2 and Mir9-3. |
