CommentsRv3132c, (MTCY03A2.26), len: 578 aa. DevS (alternate gene name: dosS), membrane-bound two component sensor histidine kinase (see citations below; dev for Differentially Expressed in Virulent strain), similar to others two component sensors e.g. Q9RI43|SCJ12.15c putative two-component sensor from Streptomyces coelicolor (585 aa), FASTA scores: opt: 1305, E(): 2.5e-69, (41.35% identity in 573 aa overlap); Q9ZBY4|SCD78.15 putative two component sensor from Streptomyces coelicolor (560 aa), FASTA scores: opt: 1194, E(): 8.1e-63, (41.05% identity in 558 aa overlap); O85371|CPRS two component regulator from Rhodococcus sp (563 aa), FASTA scores: opt: 803, E(): 8.3e-40, (38.4% identity in 552 aa overlap); Q9L094|SCC24.23 putative two-component sensor histidine kinase from Streptomyces coelicolor (similarity only in C-terminus for this one); etc. Also highly similar to mycobacterium O53473|Rv2027c|MTV018.14c putative membrane protein (573 aa), FASTA scores: opt: 2333, E(): 7.6e-130, (61.45% identity in 576 aa overlap). Predicted possible vaccine candidate (See Zvi et al., 2008). Contains GAF domain that binds heme.

ProteomicsIdentified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Translational start site supported by proteomics data (See Kelkar et al., 2011).
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).
Mutationessential gene by Himar1-based transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Required for survival in primary murine macrophages, by transposon site hybridization (TraSH) in H37Rv (See Rengarajan et al., 2005). 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).
