The mean pLDDT of this model is 64.3 (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 | 39% |
| 70 to 90 | Confident: backbone generally right | 8% |
| 50 to 70 | Low: treat with caution | 6% |
| Below 50 | Very low: often disordered regions | 47% |
What pLDDT means and how to read it
Catalyzes the phosphorylation of phosphatidylinositol 4-phosphate (PtdIns(4)P/PI4P) to form phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2/PIP2), a lipid second messenger that regulates several cellular processes such as signal transduction, vesicle trafficking, actin cytoskeleton dynamics, cell adhesion, and cell motility (PubMed:14741049, PubMed:20622009, PubMed:22942276, PubMed:9535851). PtdIns(4,5)P2 can directly act as a second messenger or can be utilized as a precursor to generate other second messengers: inositol 1,4,5-trisphosphate (IP3), diacylglycerol (DAG) or phosphatidylinositol-3,4,5-trisphosphate (PtdIns(3,4,5)P3/PIP3) (By similarity). PIP5K1A-mediated phosphorylation…
Isoform 1 interacts with TLN1 (PubMed:12422220, PubMed:14691141, PubMed:16707488). Interacts with TLN2; interaction stimulates 1-phosphatidylinositol-4-phosphate 5-kinase activity (By similarity). May compete with beta-integrins for the same binding site on TLN1 and TLN2. Interacts with ARF6 (By similarity). Interacts with AP2B1 (PubMed:19287005). Isoform 1 interacts with AP2M1; phosphorylation…
