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 last exon has been deleted from the CG42627 annotation and has been added as a first alternative exon to the CG31790 annotation in release 5.36 of the genome annotation. Annotation CG42627 has been renamed to CG43339 and annotation CG31790 has been renamed to CG43338 to reflect these changes.

                  (FlyBase Genome Annotators, 2011)

                  Annotation CG15165 split into CG31790, CG31791 and CG31801 in release 3 of the genome annotation.
