| Attribute String | Null/knockout, Reporter | Gene | Add3 |
| Transmission | Germline | Strain of Origin | 129P2/OlaHsd |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | An EGFP-pA cassette was inserted into exon 2, the first coding exon, and an FRT-flanked neomycin selection cassette was inserted into the downstream intron, which was excised by breeding to a mouse with germline expression of FLP1 recombinase, resulting in a null allele with expressed reporter and no neomycin selection sequence. |
