DSSP assignment on the reference structure.
Relative SASA
0.000.250.500.751.00
Side-chain solvent accessibility (0 = buried, 1 = fully exposed). The pipeline calls a residue surface-exposed above 0.25.
pLDDT
50.062.575.087.5100.0
AlphaFold per-residue confidence. The analysis drops residues below 60.
Curated feature
Protein-protein interfaceCatalytic / active siteLigand / substrate pocketRegulatory elementOther annotation
UniProt / literature annotation, coloured by class. Red marks a curated protein-protein interface — the independent comparison for our predicted interfaces.
Annotated interface
yesno
Curated protein-interface residue, independent of any structure prediction in this study.
Active site
yesno
Curated catalytic / active-site residue.
Inter-domain contact
yesno
Residue contacting another domain of the same protein (all-atom), so a variant effect there may be intramolecular rather than at a PPI.
HSP90 contact
TrueFalseUnknown
Contacts HSP90 in the chaperone-client cryo-EM structures ('Unknown' where the protein was not mapped).
CDC37 contact
TrueFalseUnknown
Contacts CDC37. These positions report kinase foldability rather than a canonical binding surface.
Fraction decreased
0%25%50%75%100%
Fraction of variants at this position classified decreased in this assay (2.5th-percentile rule).
Fraction increased
0%25%50%75%100%
Fraction of variants at this position classified increased in this assay.
Fraction dominant-negative
0%25%50%75%100%
Fraction of variants at this position called dominant negative: basal pathway activity below the empty-vector threshold (basal activity only).

One row per interface: complexes of the same pair and source whose interfaces overlap (IoU ≥ 0.3) are merged, as in the Fig. 6c,d volcano plots (median Cohen's d; q from the geometric-mean p). Supported: at least one complex with q < 0.05 and |d| ≥ 0.2 in either basal assay.
