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.

        ATP7 acts via copper-regulated trafficking to remove copper from cells.

        Suppression of ATP7 levels by dsRNA interference in S2 cells increases accumulation of radio labelled copper.

        dsRNA made from templates generated with primers directed against this gene used to investigate the role of this gene in copper homoeostasis in S2 cells.

        S2 cells treated with ATP7 dsRNA show significantly increased copper accumulation.
