Vesikkelitoiminnan
Vesikkelitoiminnan, or vesicle activity, refers to the dynamic processes by which tiny membrane-bound compartments known as vesicles transport and deliver molecules within cells and between cells. Vesicles originate from the endomembrane system, comprising the endoplasmic reticulum, Golgi apparatus, endosomes, lysosomes, and plasma membrane. They carry proteins, lipids, and signaling molecules, ensuring that materials reach their appropriate destinations for secretion, recycling, or degradation.
The formation of a vesicle begins with membrane curvature induced by adaptor proteins, coat protein complexes
Vesicle activity is essential for many cellular functions beyond trafficking. It facilitates signal transduction by delivering
