| Primary Identifier | MGI:4947933 | Allele Type | Targeted |
| Attribute String | Null/knockout | Gene | Trp53 |
| Transmission | Cell Line | Strain of Origin | Not Specified |
| Is Recombinase | false | Is Wild Type | false |
| description | This allele was originally generated in D3 cells containing Trp53tm1Tyj. |
| molecularNote | A loxP site flanked puromycin resistance gene cassette was inserted into intron 1. Glutamic acid codon 5 (GAG) in exon 2 was changed to a stop codon (TAG) (p.E5*). Cre-mediated recombination removed the puro cassette. |
