Protein of the Day #5: Aldehyde dehydrogenase 2

Aldehyde dehydrogenase 2, or ALHD2, is the highlight of an article in Science this week showing it is related to mechanisms for protecting the heart from ischemia (lack of blood, which results in lack of oxygen (hypoxia)). There are cytosolic and mitochondrial versions; since this protein is important in metabolizing alcohol, having both versions seems to clear alcohol faster, although I can't find a definitive reference for that fact.
