Entrez gene ID: 32001
Ensembl gene ID: FBgn0052672
Species: Fly (Taxid: 7227)
Involved in autophagy; Autophagy-specific gene 8a; Autophagy-specific gene 8a [Source:FlyBase gene name;Acc:FBgn0052672] [Ensembl]; The gene Autophagy-specific gene 8a is referred to in FlyBase by the symbol Dmel\Atg8a (CG32672, FBgn0052672). It is a protein_coding_gene from Drosophila melanogaster. Its molecular function is unknown. There is experimental evidence that it is involved in the biological process: regulation of protein ubiquitination; determination of adult lifespan; macroautophagy. 18 alleles are reported. The phenotype of these alleles is annotated with: embryonic/larval salivary gland. It has one annotated transcript and one annotated polypeptide. Protein features are: Autophagy protein Atg8 ubiquitin-like. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of moderately high expression. Peak expression observed at stages throughout embryogenesis, during late larval stages, at stages throughout the pupal period, in stages of adults of both sexes. [FlyBase]
Mutations in Atg8a results in reduced lifespan and increased sensitivity to oxidative stress while enhanced expression in older fly brains extends average adult lifespan by 56% and promotes resistance to oxidative stress .
Atg8a mutation reduces the maximum lifespan by 25% under starvation conditions .
Loss-of-function mutation in Atg8a reduces mean lifespan by 11 - 25% and maximum lifespan by 3 - 22% .
Assays: Organismal Lifespan
Mean: -25 to +56
Maximum: -3 to -25
Aging Relevance Analysis/Source:
Note: GenAge reports also another reference  which does not appear to have any data on Atg8a, right? Is the lifespan reduction only under starvation condition (GenAge does not mention it)?
