Annotation: from legacy to revised
| Legacy (H37Rv / Mycobrowser) | membrane protein |
|---|---|
| MTBC0 PGAP re-annotation | hypothetical protein |
| Revised (this work) | Conserved hypothetical protein; no recognised domain. Function unknown. |
Auto-curated: this verdict and function were generated by rules from PGAP + Pfam + Foldseek and have not been hand-reviewed.

| UniProt name | Uncharacterized protein Rv1424c |
UniProt still lists this protein as Uncharacterized protein Rv1424c; the revised annotation above is ahead of the current UniProt record.
Conservation & selection (intra-MTBC, 145 209 strains)
| pN/pS | 0.238 · purifying |
|---|---|
| Polymorphic sites (≥ 0.1% of strains) | 3 synonymous, 2 missense, 0 nonsense, 0 frameshift |
pN/pS from segregating SNPs (singletons removed) normalised by possible sites. Low pN/pS = purifying selection (a strong signal that a "hypothetical" is a real, constrained gene). A high pN/pS is ambiguous: relaxed constraint or positive selection (drug resistance, antigenic variation) inflate it; e.g. rpoB/katG/pncA score high here for resistance, not loss of function. A clonal disruption (one allele over a clade) suggests lineage pseudogenisation; a convergent one (many independent alleles) is typical of resistance loss-of-function.
Domains (Pfam, hmmscan --cut_ga)
No Pfam-A domain above the gathering threshold (or not yet scanned).
Functional interaction network (STRING v12, guilt-by-association)
Closest characterised functional partner: Rv1425 (diacyglycerol O-acyltransferase), medium confidence from genomic context alone (score 589 excluding text-mining).

diacyglycerol O-acyltransferase | 589 | 589 ctx | neighborhood:585 |
STRING combines evidence channels (neighborhood, fusion, cooccurrence, coexpression, experimental, database, text-mining) into a 0–1000 score. The ctx badge marks edges carried by the genomic-context channels (conserved neighborhood, fusion, phylogenetic co-occurrence), which are independent of orthology and structure and the strongest signal for an unknown gene. The no text-mining column recomputes the score from data alone, so a link that does not depend on the literature is visible. Association is a function hypothesis, not proof: corroborate with the operon context and the primary literature before assigning a function.
