COMPUTED STRUCTURE MODEL OF POLYMERIC IMMUNOGLOBULIN RECEPTOR

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 DB: P01833
  • Released in AlphaFold DB:  2021-07-01
    Last Modified in AlphaFold DB: 2025-08-01
  • Organism(s): Homo sapiens
  • UniProtKB: P01833

Model Confidence 

  • pLDDT (global): 76.69
  • 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.
