Gene Rv0169 (mce1)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Unknown, but thought to be involved in host cell invasion (entry and survival inside macrophages). |
| Product | Mce-family protein Mce1A |
| Comments | Rv0169, (MTCI28.09), len: 454 aa. Mce1A; belongs to 24-membered Mycobacterium tuberculosis Mce protein family (see citations below), highly similar to Mycobacterium tuberculosis proteins O07789|MCE2|Rv0589|MTCY19H5.33c|mce2A (404 aa); O53967|MCE3|Rv1966|MTV051.04|mce3A (425 aa); etc. Also highly similar to others e.g. AAD52105.1|AF113402_1|AF113402 mycobacterial cell entry protein from Mycobacterium bovis BCG (454 aa); NP_302656.1|NC_002677 putative cell invasion protein from Mycobacterium leprae (441 aa); AAA92845.1|U26018 mce gene product from Mycobacterium avium (88 aa) (similarity on C-terminus); CAC12798.1|AL445327 putative secreted protein from Streptomyces coelicolor (418 aa); etc. Note that equivalent, but longer 22 aa, to P72013|CAA50257.1|X70901 Mcep protein from Mycobacterium tuberculosis (432 aa). Contains a very hydrophobic region around residues 20-35. Note that previously known as mce1. A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004). Predicted to be an outer membrane protein (See Song et al., 2008). |
| Functional category | Virulence, detoxification, adaptation |
| Proteomics | Identified by proteomics (see Ahmad et al., 1999). Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen 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 (See de Souza et al., 2011). Translational start site supported by proteomics data (See Kelkar et al., 2011). |
| Transcriptomics | mRNA identified by RT-PCR (see Harboe et al., 1999). mRNA also identified by microarray analysis and down-regulated after 24h of starvation (see Betts et al., 2002). RT-qPCR shows higher expression of fadD5|Rv0166, mce1A|Rv0169 and mce1F|Rv0174 in M. tuberculosis H37Rv mce1R|Rv0165 mutant than in H37Rv, after infection of murine macrophages (See Casali et al., 2006). |
| Operon | Rv0168 and Rv0169, Rv0169 and Rv0170 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 and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane 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). M. tuberculosis Erdman Rv0169 mutant shows increased growth in BALB/c mice; mice infected with mutant die sooner than those infected with wild-type; BALB/c peritoneal macrophages infected with mutant produce less TNF-alpha than with wild-type; infected RAW macrophages produce less NO with mutant but similar levels of IL-4; growth in RAW macrophages is increased (See Shimono et al., 2003).
