Model Confidence 

• pLDDT (global): 95.08
• pLDDT (local):

Model Confidence 

•   Very high (pLDDT > 90)    
•   Confident (70 < pLDDT ≤ 90)    
•   Low (50 < pLDDT ≤ 70)    
•   Very low (pLDDT ≤ 50)    

Computed Structure Models provide per-residue confidence score (pLDDT) between 0 and 100. Some regions below 50 pLDDT may be unstructured in isolation.
