Also known as: atg-7; ATG-7; atg7; ATG7; CG5489; dAtg7; Dmel\CG5489
Summary: Enables Atg8 activating enzyme activity. Involved in several processes, including determination of adult lifespan; larval midgut cell programmed cell death; and positive regulation of autophagy. Predicted to be active in phagophore assembly site. Is expressed in several structures, including embryonic/larval midgut; embryonic/larval midgut primordium; salivary gland; and spermatozoon. Human ortholog(s) of this gene implicated in autosomal recessive spinocerebellar ataxia 31. Orthologous to human ATG7 (autophagy related 7). [provided by Alliance of Genome Resources, Jan 2025]

What's a GeneRIF?

Studies show that the TOR signaling pathway and ATG5 and ATG7 are crucial for the regulation of cellular processes and can play various functions in different cell types in the brain.
Title: TOR signaling pathway and autophagy are involved in the regulation of circadian rhythms in behavior and plasticity of L2 interneurons in the brain of Drosophila melanogaster.
Fasting increases survival to cold in Atg7 mutant Drosophila melanogaster.
Title: Fasting increases survival to cold in FOXO, DIF, autophagy mutants and in other genotypes of Drosophila melanogaster.
Atg7 acts downstream of Hsp27 in the regulation of eye morphology, polyglutamine toxicity, and lifespan in Drosophila.
Title: Autophagy-related gene 7 is downstream of heat shock protein 27 in the regulation of eye morphology, polyglutamine toxicity, and lifespan in Drosophila.
Atg7 mutant adults are hypersensitive to starvation and oxidative stress, live shorter, and accumulate ubiquitin- positive aggregates in the brain that lead to a progressive decline of neuronal function and cell death.
Title: Drosophila Atg7: required for stress resistance, longevity and neuronal homeostasis, but not for metamorphosis.
Atg7-/- adults are short-lived, hypersensitive to nutrient and oxidative stress, and accumulate ubiquitin-positive aggregates in degenerating neurons.
Title: Atg7-dependent autophagy promotes neuronal health, stress tolerance, and longevity but is dispensable for metamorphosis in Drosophila.
