Gene Rv1971
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Unknown, but thought involved in host cell invasion. |
| Product | Mce-family protein Mce3F |
| Comments | Rv1971, (MTV051.09), len: 437 aa. Mce3F; belongs to 24-membered Mycobacterium tuberculosis Mce protein family (see citations below), similar to Mycobacterium tuberculosis proteins O07418|Rv0174|MTCI28.14|mce1F (515 aa), O07784|Rv0594|MTCY19H5.28c|mce2F (516 aa); etc. Also highly similar to others e.g. NP_302661.1|NC_002677 putative secreted protein from Mycobacterium leprae (516 aa); CAC12793.1|AL445327 putative secreted protein from Streptomyces coelicolor (433 aa); etc. Contains a possible N-terminal signal sequence or membrane anchor. The transcription of this CDS seems negatively regulated by the product of Rv1963c|mce3R (see Santangelo et al., 2002). Predicted to be an outer membrane protein (See Song et al., 2008). |
| Functional category | Virulence, detoxification, adaptation |
| Mutant | Non-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Non-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). Check for mutants available at TARGET website |
