Gene Summary
hangover (hang) encodes a nuclear zinc finger protein that is expressed in adult fly brain neurons. Lack of hang produces a reduction of Fas2 expression. Its roles include life span, bouton growth at the neuromuscular junction and regulation of cellular stress in response to ethanol, heat and paraquat.

Gene Group (FlyBase)
C2H2 ZINC FINGER TRANSCRIPTION FACTORS -
Zinc finger C2H2 transcription factors are sequence-specific DNA binding proteins that regulate transcription. They possess DNA-binding domains that are formed from repeated Cys2His2 zinc finger motifs. (Adapted from PMID:1835093, FBrf0220103 and FBrf0155739).
Protein Function (UniProtKB)
Required for normal development of ethanol tolerance. Relies on two distinct molecular pathways: a cellular stress pathway defined by hang, and a parallel pathway requiring octopamine.
(UniProt, Q9VXG1)
Summary (Interactive Fly)

a nuclear RNA binding protein that regulates dunce transcript levels, bouton growth at the neuromuscular junction, and cellular stress in response to ethanol, heat and paraquat

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

        hang is required for ethanol tolerance development.

        RNAi generated by PCR using primers directed to this gene causes a cell growth and viability phenotype when assayed in Kc167 and S2R+ cells.

        Identification: in a behavioral screen.

        hang encodes for a zinc-finger protein required for the normal tolerance development in Drosophila. The hang gene defines a stress pathway required for ethanol tolerance in Drosophila.

        hang flies are defective in responses to several environmental stressors, such as heat and the free radical-generating agent paraquat, and display a reduced life span.
