Gene Summary
mustard (mtd) encodes an ecdysone-regulated late puff protein. A isoform including only the C-terminal with a TLDc domain enters the nucleus. This isoform increases intestinal stem cell division and suppresses expression of the antimicrobial peptide encoded by DptA at the transcriptional level, independent of IMD pathway signaling.

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.

      The 82F puff does not puff in l(3)82Fd4 flies suggesting that l(3)82Fd is the puff gene itself.

      The broad developmental expression pattern of l(3)82Fd suggests it is controlled by both ecdysone-dependent and ecdysone-independent regulatory mechanisms.
