Q-SNARE Proteins

**Definition:** SNARE proteins in which the central amino acid residue of the SNARE motif is a GLUTAMINE. They are classified separately from the R-SNARE PROTEINS where the central amino acid residue of the SNARE motif is an ARGININE. Subfamilies, the QA-SNARES; QB-SNARES; and QC-SNARES are grouped by the position of their SNARE motif-containing-domains in the SNARE complex and by their sequence similarities.
