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.

          Identified as a candidate gene for hypoxia-specific selection (via an experimental evolution paradigm) that is also differentially expressed between control and hypoxia-adapted larvae.

          Annotation (CG32629) eliminated in release 5.2 of the genome annotation.

          Annotation (CG15758) eliminated in release 5.2 of the genome annotation.

          dsRNA directed against this gene has been used in a screen for genes required for constitutive protein secretion.

          dsRNA directed against Tango13 inhibits protein secretion in S2 cells, but has no apparent effect on Golgi organisation.

          RNAi generated by PCR using primers directed to this gene causes a cell growth and viability phenotype when assayed in Kc167 and S2R+ cells.

          New annotation (CG32629) in release 3 of the genome annotation.
