Gene Rv0171
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Unknown, but thought to be involved in host cell invasion. |
| Product | Mce-family protein Mce1C |
| Comments | Rv0171, (MTCI28.11), len: 515 aa. Mce1C; belongs to 24-membered Mycobacterium tuberculosis Mce protein family (see citations below), highly similar to Mycobacterium tuberculosis proteins O07787|Rv0591|MTCY19H5.31|mce2C (481 aa); O53969|Rv1968|MTV051.06|mce3C (410 aa); etc. Also highly similar to others e.g. NP_302658.1|NC_002677 putative secreted protein from Mycobacterium leprae (519 aa); CAC12796.1|AL445327 putative secreted protein from Streptomyces coelicolor (351 aa); etc. Weakly similar to downstream ORF Rv0172|MTCI28.12|mce1D (530 aa), FASTA score: (24.6% identity in 552 aa overlap). Contains possible signal sequence and highly proline-rich C-terminus. Predicted to be an outer membrane protein (See Song et al., 2008). |
| Functional category | Virulence, detoxification, adaptation |
| Proteomics | Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate; enriched in the membrane fraction and predicted N-terminal signal peptide is uncleaved (See de Souza et al., 2011). |
| Transcriptomics | mRNA identified by RT-PCR (see Harboe et al., 1999). mRNA identified by microarray analysis and down-regulated after 24h of starvation (see Betts et al., 2002). |
| Operon | Rv0170 and Rv0171, Rv0171 and Rv0172 are co-transcribed, by RT-PCR (See Casali et al., 2006). |
| Mutant | Non-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Non-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Required for growth in C57BL/6J mouse spleen, by transposon site hybridization (TraSH) in H37Rv (See Sassetti and Rubin, 2003). Required for survival in primary murine macrophages, by transposon site hybridization (TraSH) in H37Rv (See Rengarajan et al., 2005). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
