The mean pLDDT of this model is 69.4 (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 | 31% |
| 70 to 90 | Confident: backbone generally right | 16% |
| 50 to 70 | Low: treat with caution | 25% |
| Below 50 | Very low: often disordered regions | 28% |
What pLDDT means and how to read it
Hormone that plays a central role in whole body adaptation to stress (PubMed:11329063). Released by the hypothalamus primarily in response to physical or psychological stress and acts by binding to CRH receptor CRHR2 (PubMed:20966082). UCN2-dependent signaling regulates cardiovascular function, promotes skeletal muscle hypertrophy and manage energy balance and acts as an anorexigenic agent (By similarity). In contrast to CRH and UCN, does not activate the hypothalamus-pituitary-adrenal axis to promote corticotropin hormone (ACTH) production (PubMed:11329063)
