What is the Origin of Akt Pathway?

This fundamental signaling pathway was named after the discovery of its key component, the Akt kinase, which was first identified as a viral oncogene in the late 1980s. The term 'Akt' is derived from 'Ak' thymoma, the virus in which the gene was initially found. Subsequent research elucidated its role as a serine/threonine-specific protein kinase, positioning it as a pivotal mediator in the phosphatidylinositol 3-kinase (PI3K) signaling cascade.

What is the Mechanism of Akt Pathway?

Activation begins when external stimuli, such as hormones binding to their cell surface receptors, lead to the activation of PI3K, which generates the secondary messenger PIP3. PIP3 then recruits Akt to the plasma membrane, where it is phosphorylated and activated by upstream kinases like PDK1 and mTORC2. Once activated, Akt translocates throughout the cell, phosphorylating numerous downstream targets to promote cell survival by inhibiting pro-apoptotic proteins and stimulating glucose uptake and protein synthesis, thereby influencing the metabolic environment.

Akt Pathway

Meaning

The Akt Pathway, also known as the Protein Kinase B (PKB) signaling cascade, is a crucial intracellular signaling network that regulates fundamental cellular processes, including metabolism, proliferation, survival, and apoptosis. This pathway serves as a central hub for transmitting signals from growth factors and hormones, such as insulin and IGF-1, from the cell surface to the nucleus. Its proper function is integral to maintaining cellular health and is highly relevant in the context of hormonal action and metabolic homeostasis. Dysregulation of this pathway is frequently implicated in the pathogenesis of various chronic diseases, including cancer and insulin resistance.
