Protein domain architecture

237 residues

PWWP annotation cores, other annotated regions, and deposited construct mappings share the canonical amino acid axis. The original Atlas PWWP intervals retain their source definitions.

0 additional source-supported regions · coordinates and evidence

UniProt feature coordinates accepted after exact canonical sequence identity check against the frozen Atlas. Source annotations can be inferred by sequence or curated from experiments; evidence codes remain attached. Other domain types link to their UniProt source because the Atlas records PWWP domains.

Deposited construct mapping

2 selected examples

Colored segments map deposited polymer sequences to this canonical protein; dark segments have observed coordinates. Unmapped tags and engineered residues are not assigned canonical positions. These are not certified whole-fold boundaries.

5XSKchain C1–100

Mapping and construct evidence

Deposited polymer length: 120 residues. Mapped sequence identity: 100.0%. sequence differences or tags detected; biological versus engineered origin requires review.

PWWP1: 58 / 58 annotation-core Cα residues observed.

Frozen SIFTS aligned regions with construct-to-UniProt sequence comparison. Bars are mapped canonical segments; tags, insertions, and unmapped termini are not assigned canonical positions. PDB source.

Unmapped construct positions: 1–20.

2B8Achain A1–110

Mapping and construct evidence

Deposited polymer length: 110 residues. Mapped sequence identity: 100.0%. no sequence difference detected by mapping; not proof of wild type.

PWWP1: 58 / 58 annotation-core Cα residues observed.

One mapped example per native domain, preferring frozen experimental representatives; up to four distinct mapped intervals.

Validated isoform differences · 0 PWWP correspondence records

Only source-validated PWWP core correspondences from the frozen v1.2 isoform audit; other-domain architectures are not projected onto isoforms. Coordinates in the isoform column refer to the individual isoform sequence; deleted cores remain absent.

No source-validated alternative-isoform core mapping is available in this snapshot.

Experimental coverage and AlphaFold correspondence

3 entry / domain records

One representative chain per PDB entry and native domain. RMSD uses fixed UniProt correspondence and all common Cα atoms; it is reported only for ≥40 atoms and ≥80% core coverage. A value is descriptive, not a prediction benchmark.

This retained table is the original source projection. The Phase 5 Ligands & Bioactivity section above includes added observations and reviewed target context. Values remain attached to their assay, construct and preparation. A crystal structure does not transfer affinity to another construct or stereoisomer. Assay pages preserve field-level source-verification states where reviewed; unreviewed null fields remain uncurated.
