Switch #:
SWTI000002
Switch type:
Binary
Switch subtype:
Physicochemical compatibility

Description:
Phosphorylation of S473 in the PIF motif of RAC-alpha serine/threonine-protein kinase (AKT1) by Serine/threonine-protein kinase mTOR (MTOR) (as part of mTORC2 complex) induces intramolecular interaction with the PIF-binding pocket, resulting in cis-activation of RAC-alpha serine/threonine-protein kinase (AKT1). Dephosphorylation of the PIF motif by PHLPP1/2 (PHLPP1 for Akt2/3 and PHLPP2 for Akt1/3) results in reduced Akt activity, probably by disrupting the interaction with the Akt PIF pocket and thus cis-activation.

Participants:
(1) RAC-alpha serine/threonine-protein kinase (AKT1)
