The mean pLDDT of this model is 77.6 (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 | 28% |
| 70 to 90 | Confident: backbone generally right | 44% |
| 50 to 70 | Low: treat with caution | 15% |
| Below 50 | Very low: often disordered regions | 12% |
What pLDDT means and how to read it
Required for synthesis of 60S ribosomal subunits and the transport of pre-ribosomes from the nucleoplasm to the cytoplasm. Also required for initiation of DNA replication. May function downstream of the origin recognition complex (ORC complex) in the loading of CDC6 and the minichromosome maintenance complex (MCM complex) onto chromatin during the G1 phase of the cell cycle. Essential for growth
Forms a heterodimer with NOC2. This complex may be associated with pre-ribosomal particles. Also interacts with MCM2, MCM5 and ORC1
