General annotation
Gene nametcrY
Rv numberRv3764c
FunctionSensor part of a two component regulatory system.
ProductPossible two component sensor kinase TcrY
CommentsRv3764c, (MTV025.112c), len: 475 aa. Possible tcrY, histidine protein kinase, part of a two-component regulatory system, similar to others e.g. Q9ADN6|2SC10A7.25 putative two component system histidine kinase from Streptomyces coelicolor (524 aa), FASTA scores: opt: 1332, E(): 5.4e-70, (49.9% identity in 477 aa overlap); Q9L3C1|KB|CAC42479 putative histidine kinase from Amycolatopsis mediterranei (469 aa), FASTA scores: opt: 515, E(): 1.4e-22, (36.1% identity in 313 aa overlap); P72560 histidine protein kinase from Synechococcus sp. strain PCC 7942 (Anacystis nidulans R2) (438 aa), FASTA scores: opt: 480, E(): 1.4e-20, (40.1% identity in 232 aa overlap); P30847|P76401|BAES_ECOLI|B2078 sensor protein from Escherichia coli strain K12 (467 aa); etc. Also similar to others from Mycobacterium tuberculosis e.g. P96368|Rv1032c|MTCY10G2.17 (509 aa), FASTA scores: opt: 1007, E(): 4e-51, (43.5% identity in 416 aa overlap); and P71815|Rv0758|MTCY369.03 (485 aa), FASTA scores: opt: 738, E(): 1.6e-35, (28.6% identity in 438 aa overlap). Equivalent to AAK48235 from Mycobacterium tuberculosis strain CDC1551 (506 aa) but shorter 31 aa.

Functional categoryregulatory proteins

ProteomicsIdentified in the cytosol and cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). 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 of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011).
Mutationnon essential gene by Himar1-based transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011). Found to be deleted (partially or completely) in one or more clinical isolates (See Tsolaki et al., 2004). M. tuberculosis H37Rv tcrXY mutant shows increased virulence in SCID mice (See Parish et al., 2004).
