in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Function unknown |
| Product | PE family protein PPE60 |
| Comments | Rv3478, (MTCY13E12.31), len: 393 aa. PPE60 (alternate gene name: mtb39c). Member of the M. tuberculosis PPE family, highly similar to others e.g. Q11031|YD61_MYCTU|Rv1361c|MT1406|MTCY02B10.25c (396 aa), FASTA scores: opt: 2165, E(): 1.1e-109, (85.35% identity in 396 aa overlap); MTCI364.08; MTCY10G2.10; MTCY03A2.22c; MTCY274.23c; MTCY164.34c; MTCY98.0029c; etc. Note that expression of Rv3478 was demonstrated in lysates by immunodetection (see Dillon et al., 1999). |
| Functional category | Pe/ppe |
| 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 (See de Souza et al., 2011). |
| Transcriptomics | mRNA identified by microarray analysis and down-regulated after 24h of starvation (see Betts et al., 2002). DNA microarrays 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 and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane 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 |
