Gene Rv0018c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in regulation (using dephosphorylation of a specific phosphorylated substrate). |
| Product | Phosphoserine/threonine phosphatase PstP |
| Comments | Rv0018c, (MTCY10H4.18c), len: 514 aa. PstP, phosphoserine/threonine phosphatase. Experimental studies have shown that PstP specifically dephosporylates model phospho-Ser/Thr substrates and it is likely that PknB (Rv0014c) and PstP may act as a functional pair in vivo to control mycobacterial cell growth (See Boitel et al., 2003). |
| Functional category | Regulatory proteins |
| Proteomics | Identified in the membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS; predicted integral membrane protein (See Xiong et al., 2005). Identified by mass spectrometry in whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). |
| Transcriptomics | mRNA identified by microarray analysis and down-regulated after 4h, 24h and 96h of starvation (see Betts et al., 2002). |
| Mutant | Essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Essential gene domain 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 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). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
