General annotation
FunctionUnknown. Exported protein cotranscribed with Rv3875|MT3989|MTV027.10.
Product10 kDa culture filtrate antigen EsxB (LHP) (CFP10)
CommentsRv3874, (MT3988, MTV027.09), len: 100 aa. EsxB, 10 KDA culture filtrate antigen (see citations below, especially first), highly similar to O33084|CF10_MYCLE|ML0050|MLCB628.13c 10 KDA culture filtrate antigen CFP10 homolog from Mycobacterium leprae (99 aa), FASTA scores: opt: 237, E(): 2.4e-08, (39.4% identity in 99 aa overlap). Also similar to O05440|ES6D_MYCTU|Rv3905c|MT4024|MTCY15F10.06 putative ESAT-6 like protein 13 from Mycobacterium tuberculosis (103 aa) FASTA scores: opt: 126, E(): 0.18, (23.1% identity in 91 aa overlap); and shows some similarity with other proteins from Mycobacterium tuberculosis. Contains probable coiled-coil from aa 49-93. Belongs to the ESAT6 family. Note that previously known as lhp (alternate gene name: cfp10). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).
Functional categoryCell wall and cell processes
ProteomicsCorresponds to spot 5_35 identified in culture supernatant by proteomics at the Max Planck Institute for Infection Biology, Berlin, Germany. And corresponds to spots 3874 identified in short term culture filtrate and cytosol by proteomics at the Statens Serum Institute, Denmark (see proteomics citations). 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 culture supernatant of M. tuberculosis H37Rv using mass spectrometry (See Mattow et al., 2003). Identified in the cell wall and cell membrane fractions of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified in culture filtrates of M. tuberculosis H37Rv (See Malen et al., 2007). Identified in the culture filtrate of M. tuberculosis H37Rv using LC-MS/MS; antigen recognized by serum pool from tuberculosis patients (See Malen et al., 2008). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Translational start site supported by proteomics data (See de Souza et al., 2011) (See Kelkar et al., 2011).
TranscriptomicsmRNA identified by DNA microarray analysis and possibly down-regulated by hrcA|Rv2374c (see Stewart et al., 2002). mRNA identified by RT-PCR (See Amoudy 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 for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). SCID mice infected with M. tuberculosis H37Rv Rv3874-Rv3875 mutant survive longer than those infected with wild-type (See Hsu et al., 2003). In THP-1 cells, M. tuberculosis H37Rv Rv3874 mutant is attenuated for growth and cytotoxicity; Rv3875 protein not detected by Western blot in culture filtrate of mutant (See Guinn et al., 2003).
