SNARE (Soluble N-ethylmaleimide-sensitive factor attachment protein receptor)

SNARE proteins are essential molecular machines that facilitate the fusion of cellular membranes, such as during neurotransmitter release or vesicle transport. They work by forming a tight complex that brings two membranes close enough to merge, allowing the transfer of materials or signals. SNAREs are found on both the vesicle (v-SNARE) and target membrane (t-SNARE), and their interaction ensures precise delivery and membrane fusion. This process is crucial for cell communication, cargo transport, and maintaining cellular organization, making SNAREs vital for normal cell function.
