Gene Summary
kenny (key) encodes a scaffold protein that is a component of the IKK (IκB Kinase) complex, which participates in the activation of the transcription factor Rel in the Imd pathway. This pathway regulates the antibacterial response and other less characterized cellular processes. [Date last reviewed: 2019-03-14] (FlyBase Gene Snapshot)

Gene Snapshot
kenny (key) encodes a scaffold protein that is a component of the IKK (IκB Kinase) complex, which participates in the activation of the transcription factor Rel in the Imd pathway. This pathway regulates the antibacterial response and other less characterized cellular processes. [Date last reviewed: 2019-03-14]
Pathway (FlyBase)
Imd Signaling Pathway Core Components -
The immune deficiency (Imd) pathway primarily mediates the humoral immune response to Gram-negative bacteria. Activation of the Imd pathway by diaminopimelic acid-type peptidoglycan initiates a signaling cascade that ultimately results in the release of the NFκB-like factor Rel from auto-inhibition and its translocation into the nucleus to activate the transcription of antimicrobial peptides. (Adapted from FBrf0224587 and FBrf0238555.)
Protein Function (UniProtKB)
Essential signaling component in transmitting the lipopolysaccharide (LPS) signal leading to cact degradation, which is required for NF-kappa-B (Rel) activation. Required for antibacterial immune response.
(UniProt, Q9GYV5)
Summary (Interactive Fly)

IkappaB kinase, respectively IKK regulatory and catalytic subunits - induction of antimicrobial peptide genes

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.

        key is necessary to provide immunity to reactive oxygen species-resistant pathogens.

        dsRNA made from templates generated with primers directed against this gene stops cleavage of the Rel protein product in mbn-2 and S2 cells.

        Mutant flies are highly susceptible to bacterial infections. The inducibility of Dpt but not Drs is markedly reduced in mutant flies challenged with a mixture of E.coli and M.luteus.

        Identification: as a protein that interacts with ird5 in a yeast two-hybrid screen.

        key is required for the activation of the antibacterial immune response genes.
