Gene Rv1361c (mtb39b)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Function unknown |
| Product | PPE family protein PPE19 |
| Comments | Rv1361c, (MTCY02B10.25c), len: 396 aa. PPE19 (alternate gene name: mtb39b). Member of the Mycobacterium tuberculosis PPE family of glycine-rich proteins, highly similar to many e.g. Rv1196|MTCI364.08|PPE18, FASTA scores: E(): 0, (84.9% identity in 397 aa overlap); MTCY274.23c (42.3% identity in 416 aa overlap); etc. Contains PS00501 Signal peptidases I serine active site. Note that expression of Rv1361c was demonstrated in lysates by immunodetection (see Dillon et al., 1999). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004). |
| Functional category | Pe/ppe |
| Proteomics | Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). |
| Transcriptomics | mRNA identified by microarray analysis and down-regulated after 24h and 96h of starvation (see Betts et al., 2002). DNA microarrays and qRT-PCR show higher level of expression in M. tuberculosis H37Rv than in phoP|Rv0757 mutant (See Walters 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). Check for mutants available at TARGET website |
