Expand Collapse AKT1  - General Description AKT1 is a gene that provides the code for making a protein that plays a pivotal role in important signaling pathways. These pathways help control how cells grow and divide (proliferate), survive, become able to perform specific tasks (differentiate), and eventually destroy themselves when they're damaged or no longer needed (apoptosis). AKT1 seems especially important for the normal development and function of the nervous system. When AKT1 is mutated, it may act as an oncogene causing normal cells to become cancerous. Mutations of the AKT1 gene sometimes are found in breast, ovarian and colorectal cancers. These mutations allow cells to grow without control, resulting in the formation of cancerous tumors. Somatic mutations in AKT are found in some cancers. Somatic mutations are those that instead of coming from a parent and being present in every cell (hereditary), somatic mutations are acquired during the course of a person's life and are found only in cells that become cancerous. Source: Genetics Home ReferenceThe AKT family of serine-threonine protein kinases serve as a central signaling cascade downstream of PI3K, regulating a number of processes involved in cell proliferation, survival, metabolism and angiogenesis. The activation of AKT is normally dependent on recruitment to the plasma cell membrane by PI3K activation, where AKT is phosphorylated and activated by PDK1 and mTORC2. The three AKT isoforms AKT1, AKT2 and AKT3 are known to regulate distinct physiological functions. AKT1 induces protein synthesis pathways (e.g. mTOR) and inhibits apoptotic pathways (e.g. BAD). AKT1 E17K is the major somatic gene mutation identified in the AKT family in cancers, leading to PI3K-independent membrane recruitment and deregulation of the isoform AKT1's normal specificity.
