Gene Rv3134c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Function unknown. Could play a role in the adaptation to hypoxia, participating in the phosphorelay in the two component regulatory system DEVR|Rv3133c/DEVS|Rv3132c. |
| Product | Universal stress protein family protein |
| Comments | Rv3134c, (MTCY03A2.240, len: 268 aa. Universal stress protein family protein. Ala-, Val- rich (see citations below), related to other hypothetical Mycobacterium tuberculosis proteins e.g. O53474|Rv2028c|MTV018.15c (279 aa), FASTA scores: opt: 562, E(): 3.2e-28, (40.65% identity in 273 aa overlap); O06188|Rv2624c|MTCY01A10.08 (272 aa), FASTA scores: opt: 458, E(): 1.1e-21, (36.55% identity in 271 aa overlap); O53472|R2026c|MTV018.13c (294 aa), FASTA scores: opt: 232, E(): 1.9e-07, (30.45% identity in 276 aa overlap); etc. Shares some similarity with other hypothetical proteins from Streptomyces coelicolor e.g. Q9RIZ8|SCJ1.16c (294 aa), FASTA scores: opt: 207, E(): 6.9e-06, (28.9% identity in 263 aa overlap); Q9K4L5|SC5F8.09 putative stress-inducible protein (312 aa), FASTA scores: opt: 204, E(): 1.1e-05, (28.4% identity in 271 aa overlap); etc. Equivalent to AAK47558|MT3220 Universal stress protein family from Mycobacterium tuberculosis strain CDC1551 (268 aa). Rv3134c seems cotranscribed with devR-devS (see Sherman et al., 2001). |
| Functional category | Virulence, detoxification, adaptation |
| Proteomics | Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). |
| Transcriptomics | mRNA identified by DNA microarray analysis: gene induced by hypoxia (see Sherman et al., 2001), under microaerobic and anaerobic conditions (see Mayuri et al., 2002), and down-regulated after 4h of starvation (see Betts et al., 2002). |
| 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 |
