• Nom: Akt antibody (Thr308)
• Marque: Biosynth
• Description: Akt, also known as Protein Kinase B (PKB), is a serine/threonine-specific kinase essential for regulating cellular growth, survival, metabolism, and proliferation. Functioning within the PI3K/Akt/mTOR pathway, Akt responds to signals from growth factors or insulin to help cells adapt and maintain function. There are three Akt isoforms in humans—Akt1, Akt2, and Akt3—each encoded by distinct genes. Akt activation begins when these signals bind to receptors on the cell surface, activating phosphoinositide 3-kinase (PI3K), which produces PIP3 on the cell membrane. This attracts Akt to the membrane, where it becomes fully active through phosphorylation at Thr308 and Ser473, allowing it to move within the cell to phosphorylate proteins in key pathways.Akt’s primary roles include promoting cell survival by inhibiting apoptosis through inactivation of pro-apoptotic proteins like BAD and Caspase-9. It also drives cell growth and proliferation by activating mTOR, a main regulator of protein synthesis, while suppressing growth-inhibiting pathways. In metabolic regulation, Akt increases glucose uptake and glycolysis, particularly in muscle and fat tissues, through GLUT4 translocation and hexokinase activation. Additionally, Akt promotes angiogenesis by upregulating VEGF to support tissue repair and contributes to cell migration, aiding wound healing and, in cancers, tumor spread. Its broad role in cell growth and survival often leads to hyperactivation in cancers, making it a target in cancer therapies, while its influence on glucose metabolism links it to insulin signaling, where pathway defects can lead to insulin resistance and type 2 diabetes.
