LKB1 (Liver Kinase B1)

LKB1, also known as Liver Kinase B1, is a protein that acts as a cellular energy sensor and regulator. It helps control cell growth, metabolism, and maintaining healthy cell function by activating pathways that ensure cells use energy efficiently. LKB1 is particularly important in preventing abnormal cell growth, and mutations in its gene are linked to certain cancers, like Peutz-Jeghers syndrome. Essentially, it plays a key role in keeping cells healthy and functioning properly, especially when energy levels fluctuate.
