A member of the dormancy regulon. Induced in response to reduced oxygen tension (hypoxia), low levels of nitric oxide (NO) and carbon monoxide (CO). It is hoped that this regulon will give insight into the latent, or dormant phase of infection. Induced in C57BL/6 mouse lungs 3 weeks after low dose aerosol infection with H37Rv bacteria. Was identified as a high-confidence drug target. To M.tuberculosis Rv2632c.
