Primary Identifier | MGI:6336128 | Allele Type | Targeted |
Attribute String | Conditional ready, Modified regulatory region | Gene | Rr102 |
Transmission | Germline | Strain of Origin | Not Specified |
Is Recombinase | false | Is Wild Type | false |
molecularNote | An FRT site flanked neomycin resistance gene cassette and a loxP site flanked chicken transcriptional enhancer element A that contains specific mutations in the Egr2 binding sites that prevent binding of wild-type Egr2 and instead allow binding of a mutant Egr2 (Krox20) protein, and an F3 site flanked mouse element A replaced the wild-type autoregulatory element A. Flp-mediated recombination removed the F3 flanked mouse element A and the neo cassette such that the chicken element A is expressed. |
