| Primary Identifier | MGI:4887881 | Allele Type | Targeted |
| Attribute String | Humanized sequence, Inserted expressed sequence | Gene | Il3 |
| Transmission | Germline | Strain of Origin | BALB/cAnNTac x 129S4/SvJae |
| Is Recombinase | false | Is Wild Type | false |
| description | Originally generated in ES cells containing Il2rgtm1.1Flv and Rag2tm1.1Flv. |
| molecularNote | The coding region of Il3 through Csf2 was replaced with the corresponding human sequence. The human Il3 remains under the control of the mouse promoter while expression of Csf2 is controlled by the human promoter. Cre-mediated recombination removed the selection cassettes. |
