2025 mTOR variants activation discovers PI3K-like cryptic pocket, expanding allosteric, mutant-selective inhibitor designs
American Chemical Society
Dysregulated mechanistic target of rapamycin (mTOR) signaling is implicated in various human diseases, including cancer and neurological disorders. Here, we investigate the structural dynamics of mTOR variants associated with hyperactivation, revealing a cryptic pocket akin to that in phosphoinositide 3-kinases (PI3Ks). Our findings suggest new avenues for designing allosteric, mutant-selective inhibitors targeting this cryptic site, potentially enhancing therapeutic strategies against mTOR-driven pathologies.
