General annotation
Gene nameRv3134c
Rv numberRv3134c
FunctionFunction unknown. Could play a role in the adaptation to hypoxia, participating in the phosphorelay in the two component regulatory system DEVR|Rv3133c/DEVS|Rv3132c.
ProductUniversal stress protein family protein
CommentsRv3134c, (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).

ProteomicsIdentified 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).
TranscriptomemRNA 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).
Mutationnon essential gene by Himar1-based 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 sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website
RegulonPredicted to be in the DosR|Rv3133c regulon, in M. tuberculosis 1254 (See Voskuil et al., 2003).
