The mean pLDDT of this model is 69.9 (low 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 | 35% |
| 70 to 90 | Confident: backbone generally right | 31% |
| 50 to 70 | Low: treat with caution | 6% |
| Below 50 | Very low: often disordered regions | 29% |
What pLDDT means and how to read it
Component of the ankyrin-1 complex, a multiprotein complex involved in the stability and shape of the erythrocyte membrane. Attaches integral membrane proteins to cytoskeletal elements; binds to the erythrocyte membrane protein band 4.2, to Na-K ATPase, to the lymphocyte membrane protein GP85, and to the cytoskeletal proteins fodrin, tubulin, vimentin and desmin. Erythrocyte ankyrins also link spectrin (beta chain) to the cytoplasmic domain of the erythrocytes anion exchange protein; they retain most or all of these binding functions
Component of the ankyrin-1 complex in the erythrocyte, composed of ANK1, RHCE, RHAG, SLC4A1, EPB42, GYPA, GYPB and AQP1. Interacts with a number of integral membrane proteins and cytoskeletal proteins. Interacts (via N-terminus) with SPTB/spectrin (beta chain). Also interacts with TTN/titin. Isoform Mu17 interacts with OBSCN isoform 3/obscurin. Interacts with HIF1AN. Interacts (via ANK 1-5…
