Q-snare, or Unconventional SNARE in the ER 1 homolog (S. cerevisiae), is a human gene encoded by USE1. It may also be known as: Vesicle transport protein USE1; Putative MAPK-activating protein PM26; USE1-like protein; Q-SNARE; SNARE-like tail-anchored protein 1 homolog (S. cerevisiae); D12; MDS032; SLT1. The encoded protein has an amino acid length of 259 and a mass of 29.4 kDa. Q-snare is a member of the USE1 family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Chicken.
