Function

[ESPG5_MYCTU] Specific chaperone for cognate PE/PPE proteins. Plays an important role in preventing aggregation of PE/PPE dimers.[1] [PPE15_MYCTU] May play a critical role in the homeostasis of triacylglycerol-containing lipid droplets in M.tuberculosis and influence the entry of the pathogen into a dormant state.[2]
