Target SNARE coiled-coil homology domain
IPR000727
Definition
The process of vesicular fusion with target membranes depends on a set of SNAREs (SNAP-Receptors), which are associated with the fusing membranes [[cite:PMID:9239749], [cite:PMID:9232812]]. These proteins are classified as v-SNAREs and t-SNAREs based on their localisation on vesicle or target membrane while another classification scheme defines R-SNAREs and Q-SNAREs, as based on the conserved arginine or glutamine residue in the centre of the SNARE motif PMID:9861047. Target SNAREs (t-SNAREs) are localised on the target membrane and belong to two different families, the syntaxin-like family and the SNAP-25 like family. One member of each family, together with a v-SNARE localised on the vesicular membrane, are required for fusion. The N- and C-terminal coiled-coil domains of members of the SNAP-25 family and the most C-terminal coiled-coil domain of the syntaxin family are related to each other and form a new homology domain of approximately 60 amino acids. This domain is also found in other known proteins involved in vesicular membrane traffic, some of which belong to different protein families PMID:9096343.
