About AKT2 [E17K]
AKT2 (AKT Serine/Threonine Kinase 2) belongs to the AGC kinase superfamily and is one of three closely related AKT isoforms (AKT1, AKT2, AKT3). AKT2 is activated downstream of phosphoinositide 3-kinase (PI3K) through sequential phosphorylation at Thr309 by PDK1 and Ser474 by mTORC2, driving full catalytic activation. It preferentially phosphorylates substrates bearing the RxRxxS/T consensus motif, including GSK3β, FOXO1, AS160 (TBC1D4), and IRS1, coordinating insulin-mediated glucose uptake, glycogen synthesis, and GLUT4 translocation. AKT2 plays a dominant role in metabolic tissues — liver, skeletal muscle, and adipose — distinguishing it from the more proliferative roles of AKT1. Dysregulation through PIK3CA mutation, PTEN loss, or AKT2 amplification drives type 2 diabetes, insulin resistance, and cancers including breast, ovarian, pancreatic, and colorectal malignancies. Its central position in PI3K/AKT/mTOR signaling and metabolic control makes AKT2 a compelling and therapeutically validated drug target for both oncology and metabolic disease programs.
Why PhosphoSens for AKT2 [E17K]?
AKT2 drug discovery presents several assay challenges: the enzyme requires careful lipid cofactor considerations reflecting its PIP3-dependent activation, and its high homology with AKT1 and AKT3 demands isoform-selective profiling. Traditional endpoint assays like ADP-Glo and HTRF capture only a single time point, missing burst kinetics, substrate depletion artifacts, and non-linear progress curve behavior that can obscure true inhibitor mechanism. Radiometric assays introduce safety and throughput burdens. PhosphoSens continuous fluorescent kinase assays use CSox-based peptide substrates to monitor AKT2 substrate phosphorylation in real time at physiological ATP concentrations, generating complete progress curves that reveal mechanism of inhibition, enable accurate Ki determination, and faithfully capture covalent inhibitor kinact/KI parameters — critical for next-generation AKT2 covalent allosteric inhibitors. The homogeneous, no-wash format accelerates SAR campaigns and reduces false positives common in endpoint formats.
