Enzyme Function FUNCTION: Involved in resistance to stress (PubMed:25899163, PubMed:27002134). Facilitates intracellular growth of M.tuberculosis (PubMed:25899163). Associates with and regulates lipid droplets (LDs) homeostasis under conditions of stress and may regulate non-replicating persistence (NRP) (PubMed:27002134). Could be involved in preservation of envelope integrity and tolerance to surface stress (PubMed:25899163). Has an inhibitory effect on ClgR activity (PubMed:25899163). May block ClgR activity after stress and then, form a multiprotein complex with Rv2743c-Rv2742c, leading to the release of ClgR (PubMed:25899163). {ECO:0000269|PubMed:25899163, ECO:0000269|PubMed:27002134}.

Interact With
Induction INDUCTION: Expression is regulated by ClgR (PubMed:25899163). Induced by carbonyl cyanide m-chlorophenyl hydrazone (CCCP) (PubMed:25899163). Induced by the cell envelope stressor SDS (PubMed:27002134). {ECO:0000269|PubMed:25899163, ECO:0000269|PubMed:27002134}.
Subcellular Location SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:27002134}. Note=Localizes to the surface of lipid droplets (LDs). {ECO:0000269|PubMed:27002134}.
