CG18507 is a 510-residue DUF4481-domain protein with two predicted transmembrane helices. It is likely a membrane-associated protein, but its molecular activity, organelle distribution, and biological pathway remain unresolved.
Exact input: M9PBB3, 510 residues. The accession was fetched explicitly with the gene-directory alias; no canonical-sequence substitution is made.
Raw emitted predictions: CG18507-predictions-source.json. Source features: CG18507-uniprot.txt, with an exact extraction in CG18507-sequence-evidence.json.
These are sequence/domain observations or explicitly named feature predictions, not measurements of biological function. ARBA assertions and ProtNLM-derived UniProt names are not counted as validation.

The snapshot emits names and location/keyword statements, with no GO or EC prediction for this target. Each actual statement is assessed below; no GO term has been substituted for it. Categories follow the function-prediction rubric, with nonspecific “uncharacterized” names marked UNC because they contain no testable function. CNN records an independently supported existing annotation; it does not assert a particular training-set composition.
| Kind | Verbatim emitted statement | Assessment | Evidence and limitation |
|---|---|---|---|
| Name | Uncharacterized protein | UNC | Uncharacterized protein is nonspecific and supplies no testable function. The current UniProt TMEM268 name is explicitly generated by ProtNLM and is not independent validation. |
| Location | Membrane (SL-0162) | COR | Two Phobius-predicted transmembrane helices at residues 292-310 and 316-339 provide specific sequence support for the broad membrane claim. This is an inference from membrane-spanning architecture; it does not identify an organelle or physiological function. |
No target-specific primary finding is used to establish a molecular activity here. The current assessment is bounded by exact-record architecture and the explicitly identified curated inferences.
The accession-specific GOA fetch contains no existing annotation rows. The molecular activity remains unresolved; no broad GO root or invented function is added to create apparent coverage.
Genuine external literature research is requested through the repository Falcon wrapper, with perplexity-lite configured as fallback. Provider output is retained separately as CG18507-deep-research-<provider>.md; its source leads are checked against the underlying publications and exact sequence record.
