The mean pLDDT of this model is 69.3 (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 | 36% |
| 70 to 90 | Confident: backbone generally right | 14% |
| 50 to 70 | Low: treat with caution | 15% |
| Below 50 | Very low: often disordered regions | 35% |
What pLDDT means and how to read it
Adapter protein (clathrin-associated sorting protein (CLASP)) required for efficient endocytosis of the LDL receptor (LDLR) in polarized cells such as hepatocytes and lymphocytes, but not in non-polarized cells (fibroblasts). May be required for LDL binding and internalization but not for receptor clustering in coated pits. May facilitate the endocytosis of LDLR and LDLR-LDL complexes from coated pits by stabilizing the interaction between the receptor and the structural components of the pits. May also be involved in the internalization of other LDLR family members. Binds to phosphoinositides, which regulate clathrin bud assembly at the cell surface (By similarity). Required for…
Interacts (via PID domain) with LDLR (via NPXY motifs) (PubMed:22509010). Binds to soluble clathrin trimers (By similarity). Interacts with AP2B1; the interaction mediates the association with the AP-2 complex (By similarity). Interacts with VLDLR (By similarity). Interacts with LRP2 (PubMed:23836931)
