SNARE proteins

SNARE proteins are specialized molecules inside cells that facilitate the fusion of biological membranes, such as during the process of moving materials between different parts of a cell or releasing substances outside the cell. They work by forming a tight complex that draws two membranes together, enabling them to merge efficiently and precisely. This process is essential for functions like neurotransmitter release in nerve cells and vesicle trafficking. In essence, SNARE proteins act like molecular zipper mechanisms, ensuring cellular components correctly and effectively communicate and transport materials.
