The mean pLDDT of this model is 58.8 (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 | 10% |
| 70 to 90 | Confident: backbone generally right | 15% |
| 50 to 70 | Low: treat with caution | 37% |
| Below 50 | Very low: often disordered regions | 39% |
What pLDDT means and how to read it
Transcriptional repressor that binds to the brassinosteroid (BR) response element (BRRE) 5'-CGTG(T/C)G-3' in gene promoter. Regulates positively the brassinosteroid-signaling pathway (PubMed:33324437). Mediates downstream growth responses and negative feedback regulation of brassinosteroid biosynthesis. Promotes growth. Modulates ovule initiation and development by monitoring the expression of genes related to ovule development (e.g. HLL, ANT, and AP2). Negatively regulates the abscisic acid (ABA) signaling pathway during the post-germination stage (PubMed:33324437)
Homodimer (PubMed:30287951). Interacts with BIN2 through its C-terminal fragment (PubMed:12114546, PubMed:12427989). Interacts with MKK5 (PubMed:24019147). Interacts with SAUR50 (PubMed:23020777). Interacts with B'ALPHA, B'BETA, B'ETA and B'THETA (PubMed:21258370)
