: The primary regulator of insulin-dependent glucose uptake in muscle and adipose tissue.
Somatic mutations in AKT, particularly the , alter the PH domain structure, leading to constitutive membrane localization and hyperactivation of downstream effectors like mTOR and ERK1/2. This promotes uncontrolled proliferation and resistance to apoptosis. AKT1 Transcriptomic Landscape in Breast Cancer Cells - MDPI
The PI3K/AKT/mTOR signaling axis is one of the most frequently dysregulated pathways in human disease. AKT acts as a central hub, receiving signals from receptor tyrosine kinases (RTKs) and G-protein-coupled receptors (GPCRs). Upon recruitment to the plasma membrane via its PH domain, AKT is activated by phosphorylation at T308 and S473. 2. Isoform-Specific Functions
