gORF_111295 microprotein
Antisense to a gene
existence proven (MS)
function unknown
92 aa
A non-canonical small protein (smORF) excluded from the H37Rv annotation, detected by proteogenomics with a high-confidence peptide-spectrum match. It is served here as part of a separate microproteome track: it is not one of the 3906 canonical genes and does not count in the dark stock. Its existence is proven; its molecular function is unknown. It is encoded antisense to PPE8 on the opposite strand.
Evidence & coordinates
| Detection method | MS peptide-spectrum (compendium) |
|---|---|
| Existence evidence | high-confidence peptide-spectrum match (Spectrum Forest hc) (tier T2) |
| Cross-validation | no Ribo-RET footprint at this start (Smith et al. 2022). Not informative on its own: measured genome-wide, this Ribo-RET dataset recovers only 29.1 % of annotated H37Rv starts (1136/3906), so its absence here does not argue against this microprotein — existence is already established by the MS evidence above. (P20.5) |
| H37Rv coordinates | 428109–428279 (+ strand) |
| Length | 92 amino acids |
| Shine-Dalgarno | SD absent |
| Folding free energy | 0.0 |
| Predicted localisation | Extracellular (3.402) |
| Conservation | homologues detected in Mycobacteria |
| Overlaps locus | PPE8 (Rv0355c) — by genomic geometry |
