General annotation
FunctionTranscriptional regulatory protein part of the two component regulatory system REGX3/SENX3.
ProductTwo component sensory transduction protein RegX3 (transcriptional regulatory protein) (probably LuxR-family)
CommentsRv0491, (MTCY20G9.17), len: 227 aa. RegX3, response regulator protein (sensory transduction protein) (see citations below), equivalent to O07130|RGX3_MYCBO|REGX3 sensory transduction protein from Mycobacterium bovis BCG (227 aa); AAG09797.1|AF258346_2|AF258346|REGX3 response regulator from Mycobacterium smegmatis (228 aa); equivalent to P54884|RGX3_MYCLE|REGX3 sensory transduction protein from Mycobacterium leprae (198 aa), FASTA scores : E(): 0, (95.4% identity in 197 aa overlap). Also highly similar to other response regulators e.g. AAG43239.1|AF123314_2 |AF123314 putative response regulator from Corynebacterium glutamicum (232 aa).
Functional categoryRegulatory proteins
ProteomicsProteomics shows upregulation in isoniazid-resistant M. tuberculosis clinical isolates (See Jiang et al., 2006).
MutantNon-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). Growth of M. tuberculosis Mt103 transposon mutant in BALB/c mice and in mouse bone marrow-derived macrophages is unaffected (See Ewann et al., 2002). M. tuberculosis H37Rv senX3-regX3 mutant has reduced ability to survive in THP-1 and bone-marrow-derived macrophages; mutant is attenuated in SCID and DBA/2 mice (See Parish et al., 2003).
