Structure

Protein 3D structure (Predicted by AlphaFold) (AlphaFold entry X2JC79)

If you don't see a structure in the viewer, refresh your browser.

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.
