| Image | |
| BRC No. | RBRC02759 |
| Type | Targeted Mutation Congenic |
| Species | Mus musculus |
| Strain name | B6.Cg-Atg7<tm1Tchi> |
| Former Common name | C57BL/6-Atg7 flox/flox |
| H-2 Haplotype | |
| ES Cell line | TT2 [(C57BL/6NCrlj x CBA/JNCrlj)F1] |
| Background strain | |
| Appearance | black [a/a B/B C/C] |
| Strain development | Developed by Masaaki Komatsu and Tomoyuki Chiba, Tokyo Metropolitan Institute of Medical Science. The targeting construct was electoroporated into TT2 ES cells derived from (C57BL/6 x CBA)F1. The mice were backcrossed to C57BL/6 over 5 times. |
| Strain description | Atg7, autophagy-related 7 gene floxed mice. A targeting vector was constructed by insertion of a loxP site within introns 13 and 14. Exon 14 was fused to a cDNA fragment encoded by exons 15, 16 and 17 and polyA after the stop codon. Atg7 is essential for ATG conjugation, LC3 modification systems, and autophagosome formation. Conditional Atg7 deficient mice can be generated by crossing with tissue-specific Cre mice. |
| Colony maintenance | Homozygote x Homozygote [or Crossing to C57BL/6JJcl]. Homozygous mutant mice are viable and fertile. |
