GβL also known as GbetaL, LST8, GBL, MLST8 is integral to the function of heterotrimeric G proteins, which are essential for transmitting signals from cell surface receptors to various intracellular effectors. GβL plays a crucial role in regulating the mTOR signaling pathway, which is essential for cellular growth, proliferation, and survival. Through interactions with mTOR and other components of the signaling cascade, GβL helps modulate cellular response to nutrients and growth factors, making GβL vital for maintaining cellular homeostasis and influencing metabolic processes. GβL′s primary function is to stabilize the mTOR complex, This regulation is particularly important in cancer research, as dysregulation of the mTOR pathway is often implicated in tumorigenesis.
