gORF_47860 microprotein

Antisense to a gene existence proven (MS) function unknown 55 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 tal on the opposite strand.

Evidence & coordinates

Detection methodMS peptide-spectrum (compendium)
Existence evidencehigh-confidence peptide-spectrum match (Spectrum Forest hc) (tier T2)
Cross-validationno 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.
