QOH-1, or Crystallin zeta like 1, is a human gene encoded by CRYZL1. It may also be known as: Quinone oxidoreductase-like protein 1; Protein 4P11; Quinone oxidoreductase homolog 1; Zeta-crystallin homolog; Quinone oxidoreductase-like protein 1 ; quinone reductase-like 1; 4P11; crystallin, zeta (quinone reductase)-like 1. The encoded protein is an enzyme with an amino acid length of 349 and a mass of 38.7 kDa. Other isoforms may exist. QOH-1 is a member of the Zinc-containing alcohol dehydrogenase family, Quinone oxidoreductase subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
