Summaries
Gene Snapshot
Multi drug resistance 49 (Mdr49) encodes drug transmembrane transporter that belongs to the ABCB transporter subfamily and contributes to insecticide resistance. [Date last reviewed: 2018-09-06]
Gene Group (FlyBase)
ABCB ATP-BINDING CASSETTE TRANSPORTER SUBFAMILY - FULL TRANSPORTERS -
The ATP-binding cassette (ABC) transporter family are primary active transporters that use ATP hydrolysis to drive the transport of substrates across the membrane. The ABCB full transporters encode the functional transporter in one polypeptide. (Adapted from FBrf0224053).

Structure
Protein 3D structure   (Predicted by AlphaFold)   (AlphaFold entry Q00449)

If you don't see a structure in the viewer, refresh your browser.
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.
