The mean pLDDT of this model is 89.4 (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 | 72% |
| 70 to 90 | Confident: backbone generally right | 21% |
| 50 to 70 | Low: treat with caution | 4% |
| Below 50 | Very low: often disordered regions | 3% |
What pLDDT means and how to read it
Component of the adaptor protein complex 2 (AP-2) (PubMed:14745134, PubMed:15473838). Adaptor protein complexes function in protein transport via transport vesicles in different membrane traffic pathways (PubMed:14745134, PubMed:15473838). Adaptor protein complexes are vesicle coat components and appear to be involved in cargo selection and vesicle formation (PubMed:14745134, PubMed:15473838). AP-2 is involved in clathrin-dependent endocytosis in which cargo proteins are incorporated into vesicles surrounded by clathrin (clathrin-coated vesicles, CCVs) which are destined for fusion with the early endosome (PubMed:14745134, PubMed:15473838). The clathrin lattice serves as a mechanical…
Adaptor protein complex 2 (AP-2) is a heterotetramer composed of two large adaptins (alpha-type subunit AP2A1 or AP2A2 and beta-type subunit AP2B1), a medium adaptin (mu-type subunit AP2M1) and a small adaptin (sigma-type subunit AP2S1) (By similarity). Interacts with ATP6V1H and MEGF10 (By similarity). Interacts with EGFR and TTGN1 (By similarity). Interacts with F2R (By similarity). Interacts…
