Coordinate coverage
Mapped chains
Label and author chain identifiers are kept separately. Observed Cα counts refer to each mapped annotation core.
| Protein | Label chain | Author chain | Domain | Observed Cα / core | Observed substitutions |
|---|---|---|---|---|---|
| PWWP3A | A | ["A"] | UP:Q2TAK8:PWWP1 | 62 / 62 | 0 |
| PWWP3A | B | ["B"] | UP:Q2TAK8:PWWP1 | 62 / 62 | 0 |
| PWWP3A | C | ["C"] | UP:Q2TAK8:PWWP1 | 62 / 62 | 0 |
| PWWP3A | D | ["D"] | UP:Q2TAK8:PWWP1 | 62 / 62 | 0 |

Source interpretation
Focused scientific audit
retain with stated interpretation/caveats. Observed PWWP3A core 411–472 supported; UNL identity/function unresolved. Retain review class and incomplete-side-chain warning rather than assert a defined functional ligand.
