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.

          Source for merge of: CG31904 anon-WO0149848.5

          Additional comments

          CG31904 appears to be a chimeric gene, with the 5' part of the gene derived from CG13796 and the 3' part of the gene derived from Acp1.

          "CG31904" is a putative chimeric gene derived from the "CG13796" and "Acp1" genes (where coding sequences of the two parental genes contribute to the coding sequence of the chimeric gene).

          Source for merge of CG31904 anon-WO0149848.5 was sequence comparison ( date:051113 ).
