Predicted to enable adenosylhomocysteinase activity. Acts upstream of or within S-adenosylmethionine cycle. Predicted to be active in cytosol. Is expressed in several structures, including brain; digestive system; immature eye; musculature system; and neural tube. Used to study metabolic dysfunction-associated steatotic liver disease and steatotic liver disease. Human ortholog(s) of this gene implicated in abdominal aortic aneurysm and hypermethioninemia with deficiency of S-adenosylhomocysteine hydrolase. Orthologous to human AHCY (adenosylhomocysteinase).
