	T-SNAREs (Target-Soluble NSF Attachment Receptor) is one specific part of conglomerate of [[Proteins\|proteins]] that make up cell or [[Organelles\|organelle]] [[Membranes\|membranes]], where these proteins are involved directly in [[Membrane fusion\|membrane fusion]] between, usually, the membranes of a [[Vesicles\|vesicle]] and the cell's membrane in the process of [[Endocytosis\|endocytosis]]. A T-SNARE is found on the target membrane in the [[Endocytosis\|endocytosis]] of a certain substance, where it is commonly made up of three proteins. These T-SNARES will combine with V-SNARES (Vesicle) to create a Trans-SNARE complex which is a four [[Alpha helix\|alpha helix]] bundle which is stable, this will then allow eventually the two membranes to fuse and a fusion pore to open, causing the vesicular contents to [[Diffusion\|diffuse]] into the cell. The energy for this membrane fusion is thought to come from the conformational change when the helices, from either transport or vesicular SNAREs, combine to form a complex, releasing energy.
