Predicted to enable adenosylhomocysteinase activity; identical protein binding activity; and nucleotide binding activity. Predicted to be involved in several processes, including S-adenosylhomocysteine catabolic process; chronic inflammatory response to antigenic stimulus; and circadian sleep/wake cycle. Predicted to be located in cytosol; neuron projection; and nucleus. Human ortholog(s) of this gene implicated in hypermethioninemia with deficiency of S-adenosylhomocysteine hydrolase. Orthologous to human AHCY (adenosylhomocysteinase). [provided by Alliance of Genome Resources, Apr 2022]
