ProteomicsIdentified by proteomics (See Rosenkrands et al., 2000). Identified in immunodominant fractions of M. tuberculosis H37Rv cytosol using 2D-LPE, 2D-PAGE, and LC-MS or LC-MS/MS (See Covert et al., 2001). 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 cytosol of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Detected by 2-DE and MS in M. tuberculosis H37Rv purified from phagosomes of infected murine bone marrow macrophages but not in H37Rv broth-cultures (See Mattow et al., 2006). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen 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).
Mutationnon essential gene by Himar1-based transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Check for mutants available at TARGET website
RegulonPredicted to be in the Cmr|Rv1675c regulon (See Gazdik et al., 2009).
