The mean pLDDT of this model is 60.2 (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 | 6% |
| 70 to 90 | Confident: backbone generally right | 44% |
| 50 to 70 | Low: treat with caution | 8% |
| Below 50 | Very low: often disordered regions | 42% |
What pLDDT means and how to read it
Scaffolding protein that facilitates the localization of proteins to the cell membrane (By similarity). Required for the correct formation of tight junctions and epithelial apico-basal polarity (By similarity). Acts (via its L27 domain) as an apical connector and elongation factor for multistranded TJP1/ZO1 condensates that form a tight junction belt, thereby required for the formation of the tight junction-mediated cell barrier (By similarity). Positively regulates epithelial cell microtubule elongation and cell migration, possibly via facilitating localization of PRKCI/aPKC and PAR3D/PAR3 at the leading edge of migrating cells (By similarity). Plays a role in the correct reorientation of…
Forms a ternary complex with PALS1 and CRB1 (By similarity). Component of a complex whose core is composed of ARHGAP17, AMOT, PALS1, INADL/PATJ and PARD3/PAR3 (By similarity). Forms a heterotrimeric complex composed of MMP5, LIN7B and PATJ; the N-terminal L27 domain of PALS1 interacts with the L27 domain of PATJ and the C-terminal L27 domain of PALS1 interacts with the L27 domain of LIN7B…
