    aop anterior open [ Drosophila melanogaster (fruit fly) ]

    Gene ID: 33392, updated on 17-Dec-2024

    GeneRIFs: Gene References Into Functions

    GeneRIFPubMed TitleDate
    In Drosophila, reduced insulin/IGF signaling extends lifespan by coordinating activation of Aop and Foxo. Aop and Foxo bind the same genomic loci, and individually, they affect similar transcriptional programs in vivo. In combination, Aop can both moderate or synergise with Foxo, dependent on promoter context. Also, Foxo and Aop oppose the gene-regulatory activity of Pnt.

    Longevity is determined by ETS transcription factors in multiple tissues and diverse species.
