Gene Rv0173 (mce1E)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Unknown, but thought to be involved in host cell invasion. |
| Product | Possible Mce-family lipoprotein LprK (Mce-family lipoprotein Mce1E) |
| Comments | Rv0173, (MTCI28.13), len: 390 aa. Possible lprK (alternate gene name: mce1E), lipoprotein which belongs to 24-membered Mycobacterium tuberculosis Mce protein family (see citations below), highly similar to Mycobacterium tuberculosis proteins O07785|LPRL|Rv0593|MTCY19H5.29|mce2E (402 aa); O53971|LPRM|Rv1970|MTV051.08|mce3E (377 aa); etc. Also highly similar to others e.g. NP_302660.1|NC_002677 putative lipoprotein from Mycobacterium leprae (392 aa); CAC12794.1|AL445327 putative secreted protein from Streptomyces coelicolor (413 aa); etc. Contains PS00013 prokaryotic membrane lipoprotein lipid attachment site. |
| Functional category | Cell wall and cell processes |
| Proteomics | Identified by proteomics (see Ahmad et al., 1999). Predicted surface lipoprotein - identified in culture filtrates of M. tuberculosis H37Rv; signal peptide predicted (See Malen et al., 2007). Identified in the membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS (See Xiong 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). |
| Transcriptomics | mRNA identified by RT-PCR (see Harboe et al., 1999). mRNA also identified by microarray analysis and down-regulated after 24h and 96h of starvation (see Betts et al., 2002). |
| Operon | Rv0172 and Rv0173, Rv0173 and Rv0174 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). Check for mutants available at TARGET website |
