MTOR and cancer: There are threemain families of STPs: the oxysterol-binding protein-related proteins(ORPs), the steroidogenic acute regulatory protein-related lipid transfer-relateddomain (STARD) proteins, and the Asters.1−3 STPs are potential targetsfor therapeutics against various types of cancers, neurodegenerativediseases, and viral infections due to their function in regulatingorganelle contact sites, lipid metabolism, autophagy, viral entry,and the mechanistic target of rapamycin (mTOR) signaling.4−10 Consequently, studies to address the biological functions of STPsare crucial.
