The mean pLDDT of this model is 82.8 (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 | 53% |
| 70 to 90 | Confident: backbone generally right | 30% |
| 50 to 70 | Low: treat with caution | 8% |
| Below 50 | Very low: often disordered regions | 10% |
What pLDDT means and how to read it
As a component of the GATOR2 complex, functions as an activator of the amino acid-sensing branch of the mTORC1 signaling pathway (PubMed:23723238, PubMed:26586190, PubMed:27487210, PubMed:35831510, PubMed:36528027). The GATOR2 complex indirectly activates mTORC1 through the inhibition of the GATOR1 subcomplex (PubMed:23723238, PubMed:26586190, PubMed:27487210, PubMed:35831510, PubMed:36528027). GATOR2 probably acts as an E3 ubiquitin-protein ligase toward GATOR1 (PubMed:36528027). In the presence of abundant amino acids, the GATOR2 complex mediates ubiquitination of the NPRL2 core component of the GATOR1 complex, leading to GATOR1 inactivation (PubMed:36528027). In the absence of amino…
Component of the GATOR2 subcomplex, composed of MIOS, SEC13, SEH1L, WDR24 and WDR59 (PubMed:23723238, PubMed:35831510, PubMed:36528027). The GATOR2 complex interacts with CASTOR1 and CASTOR2; the interaction is negatively regulated by arginine (PubMed:26972053). CASTOR1 and CASTOR2 convey leucine availability via direct interaction with MIOS (PubMed:35831510). The GATOR2 complex interacts with…
