COMPUTED STRUCTURE MODEL OF T-CELL SURFACE GLYCOPROTEIN CD8 ALPHA CHAIN

There are no experimental data to verify the accuracy of this computed structure model. See Model Confidence metrics below for all regions of the polypeptide chain

  • AlphaFold DBP01732
  • Released in AlphaFold DB:  2021-07-01
    Last Modified in AlphaFold DB: 2025-08-01
  • Organism(s): Homo sapiens
  • UniProtKB: P01732

Model Confidence 

  • pLDDT (global): 78.21
  • 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.
