This protein is widely expressed in various tissues including the liver pancreas and skeletal muscle. LKB1 plays an essential role in cellular energy homeostasis by phosphorylating and activating a group of at least 14 different proteins within the AMP-activated protein kinase (AMPK) family. The LKB1 protein acts as a master upstream kinase ensuring proper cellular energy balance and metabolism under conditions of nutrient stress.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nLKB1 is involved in controlling cell growth polarity and metabolism. It forms a complex with STRAD and MO25 which are necessary for its activation and function. By influencing these biological processes LKB1 regulates cell cycle arrest in response to stress signals and contributes to maintaining cellular integrity. The regulation of these processes positions LKB1 as an important factor in managing how cells respond to metabolic challenges.\u003cbr\u003e\nPathways\u003cbr\u003e\nIts function integrates into major signaling networks like the AMPK and mTOR pathways. LKB1 activates AMPK which in turn affects mTOR signaling a pathway critical for cell growth and autophagy regulation. LKB1's interaction with AMPK links cellular energy levels to the control of biosynthetic pathways and cell cycle progression. The LKB1-AMPK-mTOR axis for instance highlights the protein's role in managing how cells balance growth-related activities and energy conservation.\u003cbr\u003e\nLKB1 mutations or malfunctions are linked to Peutz-Jeghers syndrome and various forms of cancer such as lung cancer. Altered LKB1 activity affects its ability to suppress tumors primarily through its pathway interactions with AMPK and mTOR. Dysfunction in this pathway leads to unregulated cell growth and subsequently tumorigenesis. Understanding LKB1's role in these conditions aids in developing targeted therapies and diagnostic tools to manage associated risks and interventions effectively.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46845110124713,"sku":"ab266647","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab266647","provider":"Iright","version":"1.0","type":"link"}
