Research context & evidence
Target information is kept separate from product-level validation so you can review the biology and the reagent evidence independently.
PRAS40/AKT1S1 negatively regulates mTORC1 by associating with the complex and limiting substrate access under low insulin or nutrient conditions. Insulin- and nutrient-responsive phosphorylation promotes 14-3-3 binding and relief of mTORC1 inhibition.
AKT1S1/PRAS40 is studied at the intersection of AKT signalling, nutrient sensing, mTORC1 control, cell growth and metabolic regulation. Catalogue-backed reagents should be selected using product-specific species and application validation.
