in Mycobacterium tuberculosis H37Rv
General annotation
      | Type | CDS | 
| Function | Function unknown | 
| Product | PPE family protein PPE2 | 
| Comments | Rv0256c, (MTV034.22c), len: 556 aa. PPE2, Member of the M. tuberculosis PPE family, similar to many e.g. Rv0280, Rv0286, etc. Equivalent to Z98756|MLCB2492.30 from Mycobacterium leprae (572 aa), FASTA scores: opt: 1837, E(): 0, (62.9% identity in 461 aa overlap). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004). | 
| Functional category | Pe/ppe | 
| Proteomics | Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). | 
| Transcriptomics | mRNA identified by microarray analysis and down-regulated after 24h of starvation (see citation below). | 
| 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). 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 |
