Rapamycin is an antifungal metabolite of the Streptomyces hygroscopicus bacterium and among its many properties is the ability to induce autophagy — the regulated, orderly degradation and
recycling of cellular components.
Biochemistry is the study of the structure and
function of cellular components, such as proteins, carbohydrates, lipids, nucleic acids, and other biomolecules.
The finding suggests a model in which mTORC1, located at the
surface of cellular components known as lysosomes, receives «go / no - go» signals from a family of enzymes dubbed Rag GTPases.
A ring composed of actin filaments and myosin motor proteins pinches the cell apart, producing two daughter cells with equal
amounts of cellular components.
Your mitochondria, appropriately nicknamed «the powerhouse of your cells,» deteriorate with age due to ongoing exposure to toxins, which accelerate the
destruction of cellular components.
