Abstract: The present disclosure provides mTOR agonists that selectively modulate proteasome dynamics, compositions, methods and uses thereof for modulation of stress-induced proteasome dynamics and related pathological conditions. The present disclosure specifically provides therapeutic methods for treating disorders associated with cytosolic accumulation of the proteasome. The invention further provides prognostic methods for detection and monitoring drug resistant cancers, as well as methods for screening for modulators of proteasome dynamics.

Abstract: A peptide comprising the amino acid sequence set forth in WILVRLW (SEQ ID NO: 1), or any functionally related variant thereof, a complex, conjugate or chimera comprising the same, wherein the peptide is linked with or without a linker to RING or to a molecule or peptide that recruits E3 ligase and method for treating cancer by administering the same.
