The mean pLDDT of this model is 51.3 (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 | 14% |
| 70 to 90 | Confident: backbone generally right | 8% |
| 50 to 70 | Low: treat with caution | 7% |
| Below 50 | Very low: often disordered regions | 70% |
What pLDDT means and how to read it
The JNK-interacting protein (JIP) group of scaffold proteins selectively mediates JNK signaling by aggregating specific components of the MAPK cascade to form a functional JNK signaling module. JIP2 inhibits IL1 beta-induced apoptosis in insulin-secreting cells. May function as a regulator of vesicle transport, through interactions with the JNK-signaling components and motor proteins (By similarity)
Forms homo- or heterooligomeric complexes. Binds specific components of the JNK signaling pathway namely JNK1, JNK2, JNK3, MAP2K7, MAP3K10, MAP3K11, MAP3K12 and MAPK13. Also binds the proline-rich domain-containing splice variant of apolipoprotein E receptor 2 (ApoER2). Binds the cytoplasmic tails of LRP1 and LRP2 (Megalin). Binds the TPR motif-containing C-terminal of kinesin light chain, Klc1,…
