Theoretical Model: The protein structure described on this page was determined theoretically, and hence should be interpreted with caution.
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 below 50 pLDDT may be unstructured in isolation.

To the right is an AlphaFold2 3D model of SARS CoV-2 Protein NSP4 (length = 500 amino acids, i.e. YP_009725300.1, color coded by the pLDDT scores. It corresponds to the highest ranked model in terms of the pLDDT confidence scores, i.e., model 1[1].

Function

Non-structural protein 4 (nsp4)

Participates in the assembly of virally-induced cytoplasmic double-membrane vesicles necessary for viral replication[2][3]. It helps build fluid-filled bubbles within infected cells. Inside these bubbles, parts for new copies of the virus are constructed[4].
