Mtor Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The MTOR protein (Mechanistic Target of Rapamycin) is a serine/threonine kinase that serves as a central regulator of cell growth, metabolism, and autophagy. It integrates nutritional, growth factor, and energy signals to control protein synthesis and autophagy. mTOR dysregulation is implicated in Alzheimer's disease, Parkinson's disease, and tuberous sclerosis.

mTOR is a large protein with multiple domains:
mTOR exists in two functionally distinct complexes:
| Drug | Mechanism | Status |
|---|---|---|
| Rapamycin (Sirolimus) | Allosteric mTORC1 inhibitor | Approved for TSC |
| Everolimus | mTORC1/2 inhibitor | Approved for TSC |
| Torin 1 | ATP-competitive inhibitor | Research |
