The mean pLDDT of this model is 79.1 (confident overall). pLDDT is AlphaFold's per-residue confidence score from 0 to 100. In MolViewer, choose the B-factor color scheme to color the model by pLDDT, because AlphaFold stores it in the B-factor column.
| pLDDT band | Meaning | Share of residues |
|---|---|---|
| Above 90 | Very high: backbone and side chains are usually accurate | 22% |
| 70 to 90 | Confident: backbone generally right | 50% |
| 50 to 70 | Low: treat with caution | 24% |
| Below 50 | Very low: often disordered regions | 4% |
What pLDDT means and how to read it
Required for the post-translational delivery of tail-anchored (TA) proteins to the endoplasmic reticulum. Together with GET2, acts as a membrane receptor for soluble GET3, which recognizes and selectively binds the transmembrane domain of TA proteins in the cytosol. The GET complex cooperates with the HDEL receptor ERD2 to mediate the ATP-dependent retrieval of resident ER proteins that contain a C-terminal H-D-E-L retention signal from the Golgi to the ER. Involved in mitochondrial distribution and morphology
Component of the Golgi to ER traffic (GET) complex, which is composed of GET1, GET2 and GET3. Within the complex, GET1 and GET2 form a heterotetramer which is stabilized by phosphatidylinositol binding and which binds to the GET3 homodimer (PubMed:32910895)
