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.

          DNA-protein interactions: genome-wide binding profile assayed for MEP-1 protein in S2 cells; GEO accession number GSE32404.

          dsRNA has been made from templates generated with primers directed against this gene. RNAi of CG1244 disrupts the dendritic routing patterns of the ddaD and ddaE neurons, resulting in aberrantly oriented primary dendrites. The overall arborization of these neurons is reduced. Additionally, RNAi causes defects in dendrite morphogenesis.

          Additional comments

          One or more of the processed transcripts for these genes contain two non-overlapping open reading frames (ORFs). The non-overlapping ORFs are represented by CG42245 (FBgn0250911), CG1244 (FBgn0035357).
