Produktinformation

• Name: AKT antibody
• Marke: Biosynth
• Beschreibung: Akt, also called Protein Kinase B (PKB), is a serine/threonine-specific protein kinase crucial for regulating cellular functions such as growth, survival, metabolism, and proliferation. It serves as a central component in the PI3K/Akt/mTOR pathway, integrating signals required for cellular adaptation and function. Humans express three primary isoforms of Akt—Akt1, Akt2, and Akt3—each encoded by different genes. Activation of Akt starts when external signals, like growth factors or insulin, bind to cell surface receptors, which then activate phosphoinositide 3-kinase (PI3K). This cascade leads to the formation of PIP3 on the cell membrane, recruiting Akt to undergo two key phosphorylation events at Thr308 and Ser473. Once activated, Akt can travel within the cell to phosphorylate target proteins.The main functions of Akt include enhancing cell survival by blocking apoptosis through the inactivation of pro-apoptotic proteins such as BAD and Caspase-9, and promoting cell growth and proliferation by activating mTOR, a critical regulator of protein synthesis. Akt also plays a central role in metabolism, boosting glucose uptake and glycolysis through GLUT4 translocation and hexokinase activation, which is especially important in muscle and fat tissues. Additionally, Akt facilitates angiogenesis by upregulating VEGF, supporting tissue repair, and enhances cell migration, assisting in wound healing but also enabling the spread of cancer cells. Given its broad role in supporting cell growth and survival, Akt is frequently hyperactivated in cancers, fueling unchecked cell division and tumor development, which makes it a target in cancer treatments. Furthermore, Akt’s role in glucose metabolism connects it to insulin signaling, where pathway disruptions can lead to impaired glucose uptake, contributing to insulin resistance and type 2 diabetes.
