Strain Information

Image
BRC No.RBRC02759
TypeTargeted Mutation CongenicCartagena
SpeciesMus musculus
Strain nameB6.Cg-Atg7<tm1Tchi>
Former Common nameC57BL/6-Atg7 flox/flox
H-2 Haplotype
ES Cell lineTT2 [(C57BL/6NCrlj x CBA/JNCrlj)F1]
Background strain
Appearanceblack [a/a B/B C/C]
Strain developmentDeveloped 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 descriptionAtg7, 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 maintenanceHomozygote x Homozygote [or Crossing to C57BL/6JJcl]. Homozygous mutant mice are viable and fertile.
