The mean pLDDT of this model is 61.7 (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 | 19% |
| 70 to 90 | Confident: backbone generally right | 9% |
| 50 to 70 | Low: treat with caution | 34% |
| Below 50 | Very low: often disordered regions | 38% |
What pLDDT means and how to read it
Transcription factor that binds the cAMP response element (CRE) (consensus: 5'-GTGACGT[AC][AG]-3') and displays two biological functions, as regulator of metabolic and redox processes under normal cellular conditions, and as master transcription factor during integrated stress response (ISR) (PubMed:11106749, PubMed:12667446, PubMed:23624402, PubMed:8506317). Binds to asymmetric CRE's as a heterodimer and to palindromic CRE's as a homodimer (PubMed:23624402, PubMed:8506317). Core effector of the ISR, which is required for adaptation to various stress such as endoplasmic reticulum (ER) stress, amino acid starvation, mitochondrial stress or oxidative stress (PubMed:11106749,…
Binds DNA as a homodimer and as a heterodimer (PubMed:23624402). Heterodimer; heterodimerizes with CEBPB (PubMed:11018027). Heterodimer; heterodimerizes with DDIT3/CHOP (PubMed:23624402). Interacts with CEP290 (via an N-terminal region) (By similarity). Interacts with NEK6, DAPK2 (isoform 2) and ZIPK/DAPK3 (By similarity). Interacts (via its leucine zipper domain) with GABBR1 and GABBR2 (via…
